Got these 3 oopses yesterday. The machine handles logins, dns, mail, and user
web pages. Its rarely under a real heavy load. Its an AMD 5x86, ide drives,
ne2000 clone card, has been running without any hardware probs. for over a
year (in another role). Had these oopses about 5 days in on 2.0.32. Oh,
and its a fairly stock RedHat 4.2 system. Box has stayed up and been running
fine since it happened, only odd thing is port 25 has one listing in a
netstat -a as CLOSE, and one LISTENing, an artifact of the 3rd oops I suppose.
Any more info needed just let me know, like I said, its still running like
this if anybody wants me to do anything.
