We had the plugin configured for Debug ALL, as you suggested. Still no sign of an error. Apache just stops responding to all requests.
We’ve also tried to reproduce this issue by pointing the same proxy to different WebLogic clusters. Two other cluster’s don’t exhibit this behavior. It’s
tied to just the one. We’re currently combing through configurations to check for differences. At a high level, it’s the same versions of Windows, WebLogic, and Java.
Local content in Apache never causes the hang. As does content in the other apps that are being proxied.
Thanks for the help!

Subject: Re: Apache Hangs when proxying Java Requests with WebLogic Plugin
The weblogic plugin also has option to debug. Have you verified the plugin does not show the error?
Add Debug ALL and by default it should log to /tmp directory.
Are you able to serve content in other directories that may have content locally stored on Apache and that do not trigger plugin?

Hello Everyone,
I've run into a problem where Apache Hangs after several requests when proxying some Java based dashboards. Pretty consistently, the dashboard loads fine the first four or five times, on the next time Apache is hung. It just stops responding to all requests,
including the standard Apache status page. Apache never seems to come back on its own. Only when it's restarted.
The problem only happens with these java-based dashboards. It doesn't hang on other content even going out to hundreds of requests.
Apache's logs don't show an error, basically it just stops responding. It would seem like it stopped getting requests. I'd love to have an error to search on.
CPU, Memory, IO all seem to be normal like it's not doing anything.
We're running Apache 2.2.21 on Windows Server 2003, with the WebLogic Proxy Plugin. The backend server is WebLogic 10.3.3, with Java 1.6.30.
SSL is configured between WebLogic and Apache, but we're not seeing SSL errors.
Does anyone have any suggestions or comments to help resolve this error?
Thank You!
