I'm trying to find SQL statements that timed out using the SQL 2005 profiler. Is there a way to set such a filter?
In Profiler, you can add the event "Attention" under "Errors and Warnings". It's definition is
Collects all attention events, such as
client interrupt request or when a
client connection is broken.
As far as other errors (deadlocks, contraints, etc), try "Execution Warning" (reports warning that occurred during the execution of SQL statement or procedure) or "User Error Message" (the error message displayed to the user in the case of an error or exception).
Yes.
Check "All Events"
Go to the lock section
Specify the "lock: Timeout" events
Lock event in Books Online
Now, this works with server side locks (##LOCK_TIMEOUT <> 0).
I don't know if a client side timeout will be trapped.
One option, if you know what your client configured timeouts are set to (ie. 30 seconds by default), you can set a filter on your trace to only collect events with a duration greater than or equal to your timeout (minus a second or two).

I have an on-premise CRM 2016 instance and I can't receive any incoming emails inside of it even though when I run the test access says everything is good.
First, I'm unable to change a queue record email address, because I keep getting a SQL timeout error (doesn't matter how much time you increase the timeout it will never change) but if I try to change any other field it works and saves (but not the email field of course).
The same with the Mailbox's records, when I try to change the email it returns a SQL timeout error.
So what I did was change these emails by SQL queries, but after that the emails still won't create inside CRM.
It shows the next warning log in the event viewer:
35241 - The recipients for the email message with subject "[x]" in mailbox [email address] did not match any known records.
I'm running out of choices here, when I run the diagnosis tool on my organization it's performance is good but there must be something obstructing the communication with the SQL? Any clues?
SQL timeout error:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: SQL timeout expired.Detail:

I got the answer from Microsoft Community Forumns, thanks to Radu Chiribelea:
It's not enough to change the email address in SQL in it's base table for a record, so that this can be used for email tracking. There are other references as well - for example the EmailSearchBase. This is why you need to let the platform handle your changes.
You biggest issue here is the SQL Timeout and that is what you need to address. Since this occurs at a Create / Update I suspect there might be a deadlock somewhere. Do you have any plug-ins or workflows triggered at the time you create / update? If you disable those, do you still see the issue?
Can you enable a CRM Platform trace at a Verbose Level while reproducing the issue? This would give you a better overview of the actual timeout and you can then start from there to tackle it.
I'm working in a VBA module for Access that queries linked tables, generates reports based off the data, and then uses a PDF printer to save the reports to disk. There's a timer in the primary form that will, every N seconds, run an Access query against a "JOBQUEUE" table to see if there are new jobs.
If the database server becomes unavailable, this operation will of course time out. The run-time error of 3051 is being logged, and the loop will try to continue. The loop can't finish, however, because the following error comes right after the VB Run-Time error;
Title is "Microsoft SQL Server Login", so it's not within VB as far as I can tell.
Connection Failed:
SQLState: '01000'
SQL Server Error: 53
[Microsoft][ODBC SQL Server Driver][DBNETLIB][ConnectionOpen(Connect()).
Connection Failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not
exist or access is denied.
In every forum & discussion I've found that mentions this error, the asker is concerned with the cause of the error. In this case, I can assume that the error is temporary, and that it needs to continue trying to connect because the installation is unattended. Access goes into a "Not Responding..." state when it's timing out against the DB, and that's OK too, if connection is restored before it goes into the MsgBox described above, it will pick up where it left off and soldier on.
Does anyone know of a way that I can either mute that msgbox, preferably programatically, but I'd take anything at this point that can be done remotely that isn't an RDP session.
Edit: Link to image
The error I was getting was indeed not a run-time error that could be caught from code. Rather, it was SQL timing out after I already swallowed & dismissed time-outs in run-time in my VBA module.
The error does not seem to ever appear now that I have introduced a new timer that resets the loop that runs a query against my linked tables. It can't be logged & swallowed, but it can be prevented by being smarter about how I handle timeouts in run-time.
We are running a website on a vps server with sql server 2008 x64 r2. We are being bombarded with 17886 errors - namely:
The server will drop the connection, because the client driver has
sent multiple requests while the session is in single-user mode. This
error occurs when a client sends a request to reset the connection
while there are batches still running in the session, or when the
client sends a request while the session is resetting a connection.
Please contact the client driver vendor.
This causes sql statements to return corrupt results. I have tried pretty much all of the suggestions I have found on the net, including:
with mars, and without.
with pooling and without
with async=true and without
we only have one database and it is absolutely multi-user.
Everything has been installed recently so it is up to date. They may be correlated with high cpu (though not exclusively according to the monitors I have seen). Also correlated with high request rates from search engines. However, high cpu/requests shouldn't cause sql connections to reset - at worst we should have high response times or iis refusing to send response.
Any suggestions? I am only a developer not dba - do i need a dba to solve this problem?
Not sure but some of your queries might cause deadlocks on the server.
At the point you detect this error again
Open Management Studio (on the server, install it if necessary)
Open a new query window
Run sp_who2
Check the blkby column which is short for Blocked By. If there is any data in that column you have a deadlock problem (Normally it should be like the screenshot I attached, completely empty).
If you have a deadlock then we can continue with next steps. But right now please check that.
To fix the error above, ”MultipleActiveResultSets=True” needs to be added to the connection string.
via Event ID 17886 MSSQLServer – The server will drop the connection
I would create an eventlog task to email you whenever 17886 is thrown. Then go immediately to the db and execute the sp_who2, get the blkby spid and run a dbcc inputbuffer. Hopefully the eventinfo will give you something a bit more tangible to go on.
sp_who2
DBCC INPUTBUFFER(62)
GO
Use a "Instance Per Request" strategy in your DI-instantiation code and your problem will be solved
Most probably you are using dependency injection. During web development you have to take into account the possibility of concurrent requests. Therefor you have to make sure every request gets new instances during DI, otherwise you will get into concurrency issues. Don't be cheap by using ".SingleInstance" for services and contexts.
Enabling MARS will probably decrease the number of errors, but the errors that are encountered will be less clear. Enabling MARS is always never the solution, do not use this unless you know what you're doing.
I am running Access 2010 FE and SQL Server 2005 BE.
I can execute pass through queries to my SQL Server succesfully by using DSNless connections.
During my testing phase sometimes I need to restore my database to get back to my original records so I can rerun my pass through queries. What I have found is when I run a pass through query, it creates an active connection on my SQL Server. I see the connection via the SQL Server Management Console under the MANAGEMENT | SQL Server Logs | Activity Monitor, select view processes. There I can see which process ID is being used and who is using it when I run my pass through query.
Now the only way for me to restore my database is to KILL the PROCESS e.g. Active connection
Now when I have my restored database in place and re-run the pass through query, I receive a ODBC -- Call Failed message box. I have attempted to run a procedure to refresh my querydefs but to no avail, I will still get the ODBC-- Call Failed message box when I click on those objects.
Now there are two options on how to fix this problem, which in either case I find not USER Friendly.
Restart my Access Application
Wait approx 5-10 minutes to rerun the Pass Through Query
I created a function to trap my ODBC Errors and this is what appears:
ODBC Error Number: 0
Error Description: [Microsoft][ODBC SQL Server Driver]Communication link failure
ODBC Error Number: 3146
Error Description: ODBC--call failed.
So if for some reason, I need to restart my SQL server or kill a process (Active Connection) on my SQL server while the Access Application is currently connected via ODBC, the objects created via ODBC will not perform properly till I execute the 2 workaround solutions as stated above.
Can anyone shed some advice on a solution? I appreciate any insight.
I asked a similar question some time ago, and never got a satisfactory answer. My original question is here: Force SET IDENTITY_INSERT to take effect faster from MS Access
There is a registry setting documented here for ACE that controls the timeout behavior:
ConnectionTimeout: The number of seconds a cached connection can remain idle before timing out. The default is 600 (values are of type REG_DWORD).
So as a third workaround (in addition to the two you already listed) you can change that registry setting to a shorter timeout (like 10 seconds). This is the approach I took in my answer. One caveat is that shortening the timeout may cause performance or other issues. Your mileage may vary.
See my full answer to the original question for more info.
We are receiving this exception from one of our sql select statements. I cannot find error 3617 in the sysmessages table. The .Class is 25. There is no message.
We know we are getting it on Sql server 2005 servers.
I do know that this is large select that joins several tables and uses the CLR to combine and order some data.
What could be causing this error or where I could find out what the error code means?
Take a look at this: Discussion on Microsoft forums, see the answer from the moderator last in the post.
Updated: (added text from forum post):
Error code 3617 is a system attention. A system attention occurs
when the client cancels a running request. This can happen if the
command times out for example. This error is normally not sent to the
client however.
There is a special case where this can occur that you may be hitting.
When you re-use a pooled connection, the first outbound request sends
a special bit flag on the request to tell the server to reset the
connection state prior to executing the request. This bit causes the
server to first clear connection state, then execute the command. If
your SQL Server is under heavy load, and this bit is set, and it takes
a long time to reset the connection state, the client may timeout and
send the system attention. This causes the reset of the connection to
be cancelled and in this case you can see the 3617 sent to the client.
We've recently hardened this code in current release to avoid sending
back this specific error code as the error is spurious in nature
(based on timing you may or may not get this error). In any case, you
can consider this error equivalent to: "A severe error occurred on the
current command. The results, if any, should be discarded. Operation
cancelled by user."
To verify if it is this issue, examine your SQL errorlog for error
like below:
spid51 Task abort was requested while attempting to reuse a session with SPID 51, which has been reset for connection pooling. The session
will be terminated.
