How many unexplained crashes do you think your system should have?  :-)

Seriously, if you're running a release version of the OS, or are tracking the 
security branch, your machines should stay up until the power goes out and the 
UPS dies, or you reboot them.  You should be seeing hundred-day uptimes, unless 
you have hardware problems.

Yes, I read that you've swapped most of the hardware out without result; can you 
set up a second machine running the same software and configuration and see 
whether it crashes in a similar fashion (or at all)?

These don't provide any information that seems particularly relevant to 
diagnosing the problem.

[ The data says what services you're running-- apache, perl, sendmail, 
spamassassin, and suggest that your machine was idle or under a light load when 
the crashes happened.  By weak inference, that suggests against a thermal 
problem like poor CPU cooling, but I wouldn't be certain of even that. ]
