Nagios not updating/dead

Hi All!
We are running Nagios 3.0.
Today we had a problem where, more or less, Nagios was not doing
anything at all. All the services had last check times that were a
couple of hours old. Also I could not force checks through the Web-GUI.
I tried restarting Nagios, but that did not work. It wasn't until after
I rebooted that machine that things started working again. After the
reboot, we did some investigation and we found this in the Apache
error_log:
[Thu Dec 18 11:20:20 2008] [error] [client 10.2.201.228] Error opening
nagios statusfile /usr/local/nagios/var/status.dat!, referer:
x-gadget:///Nagstatus.html
[Thu Dec 18 11:20:20 2008] [error] [client 10.2.201.228] Premature end
of script headers: nagxmlstatus.cgi, referer: x-gadget:///Nagstatus.html
However, I am not entirely conviced this is related because I restarted
Apache to see if it would help with the problem, not knowing what was
going on at the moment. However, I restarted Apache *after* I restarted
Nagios. It wasn't until I rebooted the machine that these errors went
away and Nagios started working again.
I looked in nagios.log and see a definite break in the entries, the last
one being at the same time of the last check times in the GUI. Entries
did not reappear until after we rebooted.
I googled a bit but found nothing related to the error in the Apache
error_log and a couple of other searches with various key words did not
return anything useful.
Any help or info would be appreaciated.
Regards,
Jim Mohr
