[-- Attachment #1 --]
One of our servers, whose primary job is just to
serve up static web pages has been panic'ing a lot
recently.
I attach some debugging information from the three
crash cores.
There doesn't seem to be a lot of information to
go on, but any ideas that anyone might have would
be greatly appreciated.
I would be especially interested to hear if anyone
thinks that it could be a hardware problem.
There is no information in /var/log/messages prior
to the panics.
Cheers,
Ollie
