Nagios 1.0b6 not stable on sun

[Jason Ahrens]

I don't even know if FreeBSD runs on Solaris systems. Our master (the one
that keeps dying) is a Sun Solaris system on an E420.

Hmm.  I don't know FreeBSD well enough to offer expert opinion, but you
might want to investigate tuning the o/s itself.  Possibly there's some sort
of buffer overflow happening...?

Speculating wildly....  Time to pull out all the stops on tuning the o/s.
You might also want to do a truss or strace or whatever the FreeBSD
equivalent is on the master Nagios process, logging it all to a file.
Something to dissect the next time it abends.

If it's even an option, why not burn in a system with Linux and configure
that as your master?  If nothing else, you've eliminated FreeBSD as the
possible culprit.

Yet another option would be Solaris on Intel.  If that's your cuppa tea.
