JBOSS 3.2.5: 100% CPU Utilization

sandesh_kortikar Oct 7, 2004 12:14 PM

Hi,

We are using JBOSS 3.2.5 in production area. Max user connected to server are near about 100/150. The problem is CPU utilization is 100% after few hours. Client UI slows down drastically. Due to this we have only one option shut-down server & restart, Which is immposible in production area.

Can some one help me in this....

What are your jboss start parameters ?

Get a stack trace. Figure out where your application or JBoss is looped.

I've encountered the similar problem and can't deal with it.
The thing is, the amount of threads is growing unpredictably, and it's hard to figure out the reason. Maybe, it depends on JMS options (messages aren't killed immediately)?
My JBoss start options are ok.

Can anyone help me?

Why don't you use JBossProfiler on that?

You can keep the profiler off until you get the 100% of CPU, and make it active when you got the high consumption of CPU. The reports you get will tell exactly what's going on inside the JVM.

Actually I've created JBossProfiler (Well... of course I didn't have that name that time) 1 year and 1/2 ago in the same kind of problem. That's when I came developing the profiler.
