We got same problem in 3 other servers also with same version of kernel. With previous kernel we never faced this problem.

Comment 1 Prarit Bhargava 2008-09-16 12:17:15 UTC

Mikkilineni, please test with the latest kernel from 

http://people.redhat.com/vgoyal/rhel4/RPMS.kernel/

and report the results here.  A sys_times patch was previously identified as causing this error.

Comment 3 Hongguang Li 2008-09-16 18:37:21 UTC

It's easy to reproduce in our environment. When Cognos reporting service BIBusTKServerMain uses more memory, it will cause this panic.

Comment 8 Hongguang Li 2008-09-17 14:04:34 UTC

kernel-smp-2.6.9-78.9.EL.i686.rpm fixed the problem. Is kernel-smp-2.6.9-78.9.EL.i686.rpm officially supported by RedHat?

We can consistently reproduce the panic. After we apply kernel-smp-2.6.9-78.9.EL.i686.rpm the problme is gone. Is this kernel officiall supported by RedHat?

Comment 10 Prarit Bhargava 2008-09-17 14:11:17 UTC

Honguang, 2.6.9-78.9.EL is not officially supported by Red Hat.  Please contact your TAM or customer service for details.

Does 2.6.9-67.ELsmp (Red Hat Enterprise Linux AS release 4 (Nahant Update 6)) have same problem?
