JDK 1.4.2_05

I use WebLogic 8.1 on a Solaris 9 box with 8 processors. I have JDK
1.4.2_05 installed and due to long pauses with the default collector, I
tried out the Concurrent garbage collector. However, once I do that,
the system runs out of file handles within minutes of starting the load
test. Solaris is setup with 8192 as the top limit for file handles.

I tried various options within Concurrent garbage collector (like
ParNewGC, CMSParallelRemark) but all lead to system running out of file
handles.

Any inputs ?

Thanks,
Kevin.
