I am working on solr 4.2.1 jetty and we are facing some performance issues and heap memory overflow issue as well.
So I am searching the actual cause for this exceptions. Then i applied load test for different solr queries. After few mins got below errors:
WARN:oejs.Response:Committed before 500 {msg=Software caused
connection abort: socket write
Caused by: java.net.SocketException: Software caused connection abort:
socket write error
SEVERE: null:org.eclipse.jetty.io.EofException
I also tried to set the maxIdleTime to 300000 milliSeconds. But still getting same error.
Any ideas?
Please help, how to tackle this.
Thanks,
Mayur

I'm using flink mysql connector with a single executor of 32Gb RAM, 16vCPU with 32 slots. If I run a job with parallelism 32 (job parallelism 224) that is doing temporal lookup joins with 10 MySQL tables, it starts to fail after 2-3 successful runs with below error.

Did Some debugging, the process list on MySQL shows ~ 2* (total job parallelism) connections, i.e. 448 connections from Task Manager IP. The output of lsof | grep mysql-cj- | wc -l on task manager also reached to 12k from 3k. But after cancelling job, sometime this number doesn't go down. Am I missing something ?
The error is mainly because there are too many connections requesting mysql at the same time. Provide several optimization ideas for reference
Consider reducing the total concurrency of tasks
By default, lookup cache is not enabled. You can enable it by setting both lookup.cache.max-rows and lookup.cache.ttl, refer to https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/connectors/table/jdbc/
Recently we got "(Too many open files)" error in production and this leads to very high CPU spike(98%) on Linux machine and finally brought machine down. We have to reboot the machine to bring it back.
Flow of code is like this :-
Consume message from one of IBM-MQ queue -> start processing it -> make some update entries into SQL-Server DB and commit the transaction.
We are using Hikari for connection pool management and value is set as 30
hikariConfig.setMaximumPoolSize(30);
While checking the logs, i found following stack trace :-

I am confused here what leads to max open files error here :-
is it due to Hikari CP as this is first line we got as an error (java.io.FileNotFoundException: /opt/apache-tomcat-7.0.88/webapps/ROOT/WEB-INF/lib/HikariCP-2.5.1.jar (Too many open files) ) ?
Is it due to IBM-MQ connection not available ?
You could use the lsof command to LiSt Open Files.
It produces lots of output, so you'll want to capture and post process it ( eg grep or sort)
You can list open files by pid, userid, disk etc.
You might try lsof > before wait... lsof > after then use diff to see the differences
I am seeking if you can help in with the below error that is been thrown. I have tried to increase the heap size but it is still complaining about the same.
The process file endpoint doing the decryption of 3GB file size and more.., and it complaints about it, but with other files, it worked fine.
I am wondering why the the, in case of the heap issue, I am seeing null, , i.e
I have tried to gave the heap size upto 8GB still process complaint about it. I guess it may not be related to the JVM heap, I may request your input what would be the possible cause of it and any remediation can be done on.

I have a very simple ftp route that should recursively download files from an URL. It would be very important to get it running still today.
There are no proxies, no extra authentication, no firewall. However, it only downloads the first file and then the socket will be closed. I have experimented with the different timeouts but they did not solve the issue. Either error code 226 is retuned if I don't use any timeout or extra config option or if I use the commented out things, error code 221 is returned. The 226 does not seem to be an error as it just counts as an indication that the server completed the transfer. Stack traces I copied below. I would appreciate the responses and thanks also in advance.
The route I am using in pollEnrich as I have to start it depending on a timer.
The code:
[...]
from("direct:ftp").routeId("ftp")
.log("### FTP is in progress ")
.pollEnrich().simple(ConfigData.getConfigData().getFtpUrl()
+ "?binary=true&"
+ "recursive=true"
/* + "soTimeout=300000&"
+ "stepwise=true&"
+ "ignoreFileNotFoundOrPermissionError=true&"
+ "ftpClient.dataTimeout=30000&"
+ "disconnect=true&"
+ "consumer.delay=1000" */
)
.to("file:modelFiles")
.end();
[...]
Update 1
I removed pollEnrich() and without it it works fine. However, I cannot start it from another route e.g. from a timer. So this is a quick hack to get FTP running. I also copy the code here as I did it with an idempotent consumer, so that only those files will be downloaded that are not yet on the disk. It can maybe be useful also to other people. The idempotent consumer example you can find here (Apache Camel ftp consumer loads the same files again and again) for more information.
Any further comments?
from(ConfigData.getConfigData().getFtpUrl()
+ "?binary=true&"
+ "recursive=true&"
+ "passiveMode=true&"
+ "ftpClient.bufferSize=10000000&"
+ "localWorkDirectory=" + ConfigData.getConfigData().getLocalTmpDirectory())
.idempotentConsumer(header("CamelFileName"), FileIdempotentRepository.fileIdempotentRepository(new File("data", "repo.dat")))
.to("file:modelFiles")
.log("Downloaded file ${file:name} complete.")
.end();

Solution:
As added in Upadete 1, I do not use pollEnrich(). The route cannot be started from a timer now but it works. So I will close the question. I really like the idea of the idempotent consumer (unrelated to the original question).
Don't forget that a pollEnrich delete the oldExchange and keep the newExchange.
So you don't want to do a from("ftp").pollEnrich("timer") but a from("timer").pollEnrich("ftp").
See the Solution at the end of the question.
StateMachineBase.java is not updating. I've tried moving the file so that the designer should re-create it, I've tried running it from the command line (no error messages are displayed).
Is there anything I can do to troubleshoot designer.jar and the StateMachineBase.java file?
the designer.jar file has a last modified date of Sept 1, 2015. I normally work in IntelliJ Idea but given that I'm running the designer from the command line, I assume this helps eliminate the IDE from the equation.
What steps can I take to troubleshoot this? what files or settings could affect the behavior of the Designer as it writes the StateMachineBase.java file?
Here is the contents of my codenameone_settings.properties file:

Check the output of the designer when running it from the command line.
Make sure your codenameone_settings.properties is a valid file and contains the following.
This must point at a valid res file which must be the one containing your GUI's:
guiResource=theme.res
This must point at the generated package for the StatemachineBase.java:
package=generated
This must point at the StateMachine.java source file, not as crucial but important:
userClass=src/userclasses/StateMachine.java
This must point at a valid main form within your GUI:
mainForm=Main
You can try and regenerate the state machine directly from the command line using the command:
java -jar path_to_designer_1.jar -regen path_to_resfile.res
I'd really like to know if that works or fails.
