Nagios 3.06 Died upgraded to 3.1.0

Nagios Nagios Configuration support
1

I have had nagios installed since the 1.x days with minimal issues, but I left on Friday, nagios was up and running! I get into the office to realize that nagios is not running I run the command service nagios checkconfig eveything looks ok so I start it with service nagios start and get Starting nagios: done.
I check the log file and get
[1234887556] Nagios 3.1.0 starting… (PID=8277)
[1234887556] Local time is Tue Feb 17 10:19:16 CST 2009
[1234887556] LOG VERSION: 2.0
Which is normal, but if I do a ps -A |grep nagios nothing nagios.lock shows the pid same as the log. Any ideas on this
Thanks in advance
