Odd "RESTART" service check problem................

[Emmett Hogan]

Hi Folks,

We had an odd problem this weekend, and I am wondering if anyone else 
has seen the same thing.

We are running Nagios v2.0b1 on a Debian box.

We had to take a bunch of machines down, so we turned off all service 
and host checks...from the logs:

[02-06-2005 19:40:45] EXTERNAL COMMAND: STOP_EXECUTING_HOST_CHECKS;
[02-06-2005 19:39:57] EXTERNAL COMMAND: STOP_EXECUTING_SVC_CHECKS;

After the maintenance was done, we restarted host and service checks:

[02-06-2005 22:13:45] EXTERNAL COMMAND: START_EXECUTING_HOST_CHECKS;
[02-06-2005 22:13:45] EXTERNAL COMMAND: START_EXECUTING_SVC_CHECKS;

As luck would have it, we had a server problem later that night which 
Nagios failed to catch with a simple "http_check".

So........I went back through the web server logs looking for the nagios 
checks (we have two going to the same machine checking two different 
backend services).  One of the services was being checked just fine, but 
the other (of course the one that later went down) was not being checked 
at all AFTER the restart of svc checks!  Once I restarted the Nagios 
process the checks started happening again.

Needless to say, we are wondering what other services were not being 
checked.

Has anyone else experienced this? Where seemingly random services are 
not getting checked after a "START_EXECUTING_SVC_CHECKS" command?

Thanks,
-Emmett
