JBoss 7.1.1 is getting Slow down, need to restart for each two days

[ramakoteswar]

We recently upgraded to JBoss 3.2 to JBoss AS 7.1.1. We are also facing exactly same issue. We need to restart the server every  two days. Our application with EJBs and doesn't have Spring even facing the issue. It seems it is not an issue related an application or CPU, it is related to server. We tried some configuration on server by changing VM arguments like  TieredCompilation and ReservedCodeCacheSize for performance,http://xmlandmore.blogspot.de/2012/04/performance-tuning-with-hotspot-vm.html, even we haven't find any solution other than restarting the server. We tested memory peaks and CPU usage on JConsole in local system and all are in limits. But in Production the issue is repeating.

Please let us know if any advancements or solutions regarding this issue.

Thanks in advance

Do you monitor the GC with GC logging? Also you might use "jstat -gccause <pid>" to have a view how the memory is used.

Could it be application related? Maybe more load or batch at this time?

Sometimes the reason is a bit before the server starts getting slow.

I don't see whether the server itself can be the reason, but you might upgrade to a newer version as this version is older and there are bugfixes and enhancements which might help.

Hi Wolf-Dieter Fink,

Our application has EJB 2.0. Does it effect the performance of Jboss 7.1 ?

There are some issues with EJB2, but I'm not aware of such one. All these issues are more functional and does not end in such decrase after a time.

As there is a lot of time between AS3.2 and AS7 there are lots of changes which might have bugs or cause issues which need updates.

You need to elaborate what the reason is by checking whether it is a memory issue or something else.
