[Wrapper-user] JVM appears to be hung message.

[Tasso A. <ta...@rb...>]

Sorry for the repost but message got blocked because it was too big.

 

This is General question...

 

I started stress testing my application and after a couple of hours I
got...

 

ERROR  | wrapper  | 2010/08/05 06:31:12 | JVM appears hung: Timed out
waiting for signal from JVM.

ERROR  | wrapper  | 2010/08/05 06:31:13 | JVM did not exit on request,
terminated

 

My profiler showed that I had reached the maximum heap. But the app
should have recorded an OutOfMemory exception. I would have seen it in
the wrapper.log right? Or is it because I used 32 bit wrapper with 64bit
vm?
