Subject: seeing some "Bad page state in process.." msgs....
Date: Mon, 10 Nov 2008 14:43:55 -0500 [thread overview]
Message-ID: <49188EFB.7070601@atl.lmco.com> (raw)
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?
