Multiple server lockups 2003-06-10 - By Douglas K. Fischer

Over the past week I have had 3 different production web servers lock up
with no errors, warnings, or any other indications in any log, process
accounting, anything (I combed the systems high and low for any indication
of any abnormal behavior, but everything checks out perfectly fine,
including hardware diagnostics). They are all Dell PowerEdge servers, but
different models, different hardware, etc. They all share the same Red Hat
7.2 configuration. They went through a quarterly patching update in early
May (including an update to kernel 2.4.18-27.7.x), followed by a security
update at the end of May (including an update to kernel 2.4.20-13.7).
Has anyone else experienced any such problems with the recent Red Hat
errata? The only changes to the systems have been these updates. I'm
hesitant to rollback all these updates, given the security implications,
but I don't know if I'm going to have any other option if I can't narrow
down the problem.
Thoughts? Ideas? Suggestions?
Many thanks,
Doug
