The logs don't reveal much, as it appears you system was already out of 
memory or file descriptors right after Nagios started.

A few minor leaks from valgrind have just been fixed in my latest CVS 
post, but that's because I just rewrote 4k+ lines of macro code. Ugh. 
Current CVS code might break if you nudge it just the right way - I'll 
be finishing up loose ends on the macro code rewrite and testing tomorrow.

I noticed several leaks from embedded Perl.  That could be the cause of 
the problem over a long period of time.

The question that comes to my mind though: why was your system out of 
mem/files when Nagios started.  Usually if Nagios is the cause of such 
problems, they'll disappear once the Nagios daemon is shutdown.  Perhaps 
there was still a copy running somewhere?
