NRPE_NT Randomly Stops

Yup, every day or so we’ll get connection refused errors from NRPE on one of our NT hosts. When we look into the log files, we find this error from VsJITDebugger:

An unhandled win32 exception occurred in NRPE_NT.exe [1508]. Just-In-Time debugging this exception failed with the following error: Debugger could not be started because no user is logged on.

Check the documentation index for ‘Just-in-time debugging, errors’ for more information.

Going to that URL is no help, as Microsloth reports no known issues related to this error. Any ideas as to why this could be happening? Googling isn’t getting me anywhere, either…

We’ve got a service called “Monit” that I could use to check NRPE and restart it whenever this happens, but I’m curious as to why this is happening at all.
