Nagios Support Forum

Summary:
I am running a new instance of Nagios on Ubuntu and am getting the following error when I "reschedule the next check of this service" for a Windows NCPA agent. However, if the Nagios server waits 5 minutes, all the errors are cleared. Then, between between the all cleared errors and 5 minutes, the error comes back, then the cycle starts over.
error:
(No output on stdout) stderr: /bin/sh: 1: Syntax error: Unterminated quoted string

Setup:
