[JBoss-user] JBoss 3.2.2 process takes 100% CPU on HPUX11

[Sasidharan, M. <Man...@pl...>]

Hello All,

OS: 		HPUX11 
JVM: 		1.4.2.00 
JBoss: 	3.2.2

One of our multi-user test hangs JBoss v3.2.2 and the process takes 100%
CPU. There is no way to take a thread dump as the process does not respond.

We were able to take thread dumps of a client process. Can somebody give any
clue on what could be wrong. 

The test is repeatable and hangs the server in 15 minutes. If there is any
way to turn on some debugging/tracing to get more details, please let us
know.

Thanks in advance.

Best Regards
MS
