Description of problem:
Across a variety of server hardware (IBM eServer 330, Dell PE1750, Dell PE2650, Dell PE2550, AMD64 dual opteron system) I've been seeing a large number of kernel Oopses over the past several weeks.  The systems will keep running at first, but usually end up locking up once Oopsing has started.  Looking over my logs, I have 134 logged oopses since Feb 28th spread over 28 different systems.

Of those 134, 49 appear to be initiating with kswapd; the others are reported from somewhat random other processes (often multithreaded java-based applications) after a kswapd oops has occurred on the running kernel.

I've read through the current list of 'kernel oops' bugs (I really have) and haven't found anything substantially similar, but I've missed dups before, and I apologize if that's the case. If nothing else, I have a large quantity of data available on these oopses.

Version-Release number of selected component (if applicable):
kernel-2.6.10-1.9_FC2smp  kernel-2.6.10-1.14_FC2smp  2.6.10-1.770_FC2smp

How reproducible:
Sometimes

Steps to Reproduce:
1. Run memory intensive, multithreaded applications
2. Wait
3.
  

Actual Results:  Kernel Oopses and eventual hang.

Expected Results:  User app can crash if neccessary, but the kernel should go on.

Additional info:

I'll attach one set of representative log messages, plus a combined syslog listing grepped for 'Process: ' in case someone would like to request others.
