The first line is normal and happens during rc.local - just after a 
successful boot.  9 seconds later nagios sends it first queries out 
which die - still looking at which they were exactly.  At the 5 minute 
mark, cacti polling happens which also dies.  SEC killed both the 
processes as soon as it saw "Bad page state in X" so that I could 
actually read some this this time.

Let me know if you need more info.

Thanks,
Brian
