I use Nagwin more then 3 months, everything work good, but now nagwin starts periodically stop to check hosts and services. I check eventviewer I didn't find nothing special. I reboot server, after Nagwin start check the hosts and services.
Somebody have any ideas
You may check log files at var/log directory for possible reasons of failures.
I checked,I didn't find nothing special
If it worked for you for a long time and stopped suddenlt to work, you may need to look the problem somewhere else: That could be an intrusive windows update. There are also a large list of applications which may interfere operations of Cygwin which Copssh is dependent on.
I checked log file then nagwin stop check services and hosts, I find this log:

Warning: Service performance command 'process-service-perfdata' was not found - service performance data will not be processed!
Sorry for a late update. Those messages alone shouldn't cause an abnormal behaviour except performance data. You may consider to turn off performance logging in nagios.cfg.
