Description Markos Gogoulos 2008-03-18 18:43:50 EDT
Description of problem:

in our Scientific Linux cluster (SL 4.5 64bit) we have received the following
two errors:

wn014: Mar 12 09:09:20 wn014 kernel: knot[24574] trap divide error rip:405894
rsp:7fbfffe520 error:0

wn057: Feb 27 04:31:44 wn057 kernel: fs[4851]: segfault at 00000000ed410c22 rip
00000033ed3707b0 rsp 0000007fbfffb2a8 error 4

Errors are repeated many times (each 4-5 seconds) and appear every few days on
most of the nodes. 

Version-Release number of selected component (if applicable):


How reproducible:

All nodes have 2.6.9-67.0.4.ELsmp x86_64 kernel and run a small set of ordinary
services, plus a gpfs client software to mount a gpfs filesystem. Could the last
one be creating the issues?
Steps to Reproduce:
