[Performance Tuning] - Re: Full GC not releasing Memory

by PeterJ

It might help. But you really first need to find out where the threads are being allocated, and especially for JBoss AS ask yourself if you really need as many threads as you are allocating.

[Performance Tuning] - Re: Full GC not releasing Memory

by vons1234

Hi Peter, I think OS ran out of room while allocating memory for threads. I am using thread stack size as -Xss128k and when i do ulimit -s on linux it shows 10240. Increasing ulimit for thread will help???

[Performance Tuning] - Re: Full GC not releasing Memory

by PeterJ

Each thread uses 1MB of memory (at least, I think that is the default - it keeps on changing and is different for each OS) - looks like you ran out of available memory (there is also the possibility that the OS ran out of room within its memory area to allocate another thread). You could try reducing the thread stack size using either the -Xss or -XX:ThreadStackSize=n options.

[Tomcat, HTTPD, Servlets & JSP] - Re: Referencing ${catalina.base}

by PeterJ

I see catalina.base in 4.2.3, but not in 5.1.0. But 5.1.0 does have catalina.home. You can check out all of the available system properties using the jmx-console, looking at the jboss:type=Service,name=SystemPrtoperties MBean. You could either change the config file to use another system property, or add the system property to the command line, or configure the system property service (see the server/xxx/deploy/properties-service.xml file) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240882#4240882 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4240882

Peter, The hello world heap dump is working Thanks!, I will run the jmap again for jboss process and will wait to see how long it takes, My Heap size is 1G, i think it will take at least 10-15 mins to dump that.

[JBoss Tools (users)] - Re: Cannot open .jsp files on Eclipse 3.2.4

by mareshkau

Eclipse is 3.2.4 is very old release of eclipse. It's better to you update on new version (eclipse 3.5) from eclipse.org. Also you can add to eclipse jboss tools or use jboss studio.

Yes that's correct Peter, I am running jmap with same account under which Jboss is running. That's a good idea to run with hello world first.

[Performance Tuning] - Re: Full GC not releasing Memory

by PeterJ

Are you running jmap with the same account under which JBoss AS is running? Also, it might take a while to dump a large heap. If none of that helps, try dumping a simple hello world java app and see if that works.
