Subject: seeing some "Bad page state in process.." msgs....

I am running 2.6.26.6-rt11-1.2944.fc6.emulab-highmem #1 SMP PREEMPT RT

My test pgm is a java pgm that has about 650 threads in it (i am doing some stress testing). This test runs w/o any 
kernel messages when run on vanilla 2.6.25 kernel. But w/ the above RT kernel I see some kernel msgs that I do not 
understand.

ANy hints?
