Exact message both times, different CPU. This was running on a brand new Dell Poweredge 1950. Two other identical servers, also new, running 2.6.9-67.0.7.ELsmp & 2.6.9-67.0.15.ELsmp have no issues. The mgeDAE mentioned in the message is the UPS monitoring utility using SNMP to communicate with it. Same tool runs on other PE1950s with no issues.

Could you please try 78.1 or 78.2 from http://people.redhat.com/vgoyal/rhel4/RPMS.kernel/ and report back with results. The sys_times patches were reverted in 78.1. Thanks, P.
Downloaded and installed 78.2 and will update in a day or two. Vic
No kernel panic as yet so it must have been the sys_times patch :( You can close this bug if you wish. Vic.
