Installing Google Appengine on Windows 7 - google-app-engine

My Windows Vista Laptop is dying so I purchased a new HP Laptop running Windows 7 Pro 64 Bit.
I then downloaded and installed python-2.7.8.amd64.msi. Followed by GoogleAppEngine-1.9.9.
Copied my Google App Application from the Vista Laptop to the Win7 and tried to run it. The problem is that more often than not Chrome just displays a blank page and the App Launcher Log shows a mammoth entry, shown below. Refreshing the Chrome screen sometimes displays the page correctly, sometimes it takes 3 or 4 attempts. (Note that this problem is across a couple of projects and all .html screens within them)
So, my question: any thoughts on what I have done wrong here?
The log reads ...

Out of frustration I updated to Windows 8 (came on cd with new laptop) and then 8.1.
Problem seems to have gone.

Module status keeps running after it has been disabled

I rebooted my linux machine and started noticing these odd requests in my Apache access log.
::1 - - [16/Dec/2020:21:28:54 -0500] "GET /server-status?auto HTTP/1.1" 404 147 "-" "Go-http-client/1.1"

::1 - - [16/Dec/2020:21:29:58 -0500] "GET /server-status?auto HTTP/1.1" 404 147 "-" "Go-http-client/1.1"
I did some research on how to disable these requests and discovered they are part of a Apache module called "status". I disabled it, it when I run a2dismod status it appears to be disabled:
Module status already disabled
How can I get these requests to stop other than blocking them? I'd rather not have my access log filled with garbage.

You can use SetEnvIf:
SetEnvIf Request_URI "^/server-status?auto$" dontlog
More details here:
https://www.howtoforge.com/setenvif_apache2
Or you can find why you have requests and disactivate it. Maybe a monitoring system ?

pgadmin 4 v 1.5.2 not starting in windows 8.1

I had installed pgadmin 4 - v1.5.2 on system with Windows 8.1 Enterprise 64bit Os. When I start pgadmin it's stuck with message - "Loading pgAdmin4 v1.5...". To troubleshoot I had made below changes to config_local.py.
Disable upgrade
Enable debug mode.
Set SERVER_MODE = False
Please find the last few lines of the logs and attached screenshot.

I works with a direct Internet connection.
I'm under Ubuntu 14.04.

EDIT Looks like there is a defect in the SDK around using a proxy with URLFetch.
https://code.google.com/p/googleappengine/issues/detail?id=544
Try setting the uppercase versions of those environment variables, HTTP_PROXY and HTTPS_PROXY. The gcloud launcher requires them that way so I assume goapp does as well.
Using an HTTP proxy
If you are running gcloud preview app behind an HTTP proxy, you must
tell gcloud preview app the name of the proxy. To set an HTTP proxy
for gcloud preview app, set the http_proxy and https_proxy environment
variables. Note that you must specify the full path for the app.yaml
file.
Using Windows (in Command Prompt):
$ set HTTP_PROXY=http://cache.mycompany.com:3128
$ set HTTPS_PROXY=http://cache.mycompany.com:3128
$ gcloud preview app deploy DIRECTORY/app.yaml
Using the command line in Mac OS X (in Terminal) or Linux:
$ export HTTP_PROXY="http://cache.mycompany.com:3128"
$ export HTTPS_PROXY="http://cache.mycompany.com:3128"
$ gcloud preview app deploy DIRECTORY/app.yaml

Camel-swagger and Hawt.io incompatibility

We have Camel (2.15.2) based application with some REST services published.
Camel-swagger component is used to publish information about the services.
Everything works perfectly if the app is alone in a Tomcat container.
127.0.0.1 - - [12/Jun/2015:11:25:20 +0200] "GET /myapp/api-docs/ HTTP/1.1" 200 383
However if I deploy freshly downloaded Hawt.io 1.4.51 WAR (sample-1.4.51.war) in the same container (no changes o configurations done) I get 204 response code from my original app.
127.0.0.1 - - [12/Jun/2015:12:50:51 +0200] "GET /myapp/api-docs/ HTTP/1.1" 204 -
I guess it all about JMX and how Swagger gets information about REST services published in the Camel context, but I not sure how to avoid this error

Getting consistent, immediate backend shutdown on Google App Engine

Whenever I try to start a task on my GAE backend, its gets shutdown almost immediately. I've looked at the documentation regarding the reasons for shutdown but I can't determine the cause. The is no evidence of excess CPU or memory. It happens every time.
I added the shutdown handler and it is getting invoked. Before I put in the handler, I got no log entries from my code, only the "Process terminated because the backend took too long to shutdown" message. Now with the handler I get the initial log entry and the exception that results from the interruptAllRequests call in the handler.
Any ideas?

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

I'm solved the issue by changing the backend class from B1 to B4. That leads me to believe it was a memory problem even though I there are no specific indications of that. I see that on the Python side there are easy methods to check CPU and memory. Are there Java equivalents?
