Good morning,
In my windows machine Windows 2008 R2, Nsclient service stops with the following error:
The NSClient++ (x64) service terminated unexpectedly. It has done this 1 time(s).

In the nsclient.log

Why is agent nsclient stopped?
My nsclient version is NSClient++ - 0.3.9.328
Thanks for your time.
Regards.

The WinHTTP Web Proxy Auto-Discovery Service has been idle for 15 minutes, it will be shut down.

Does this service influence NSCLIENT?

It's possible that this error is associated with the windows performance counters. You can try rebuilding them by running on the windows box at the command prompt:
http://support.microsoft.com/kb/300956

then restarting the nsclient++ service. If the issue doesn't go away, check the log again for new errors.

I've restored the counters but the problem persists
In the nsc.ini i have:

; Restart service if a crash is detected

restart=1

But when nsclient down, does not start automatically.

What is this restart?

Thanks.
Regards

I have this error in the event view.

"Faulting application nsclient++.exe, version 0.0.0.0, faulting module CheckSystem.dll, version 0.0.0.0, fault address"

Where is the problem?

Thanks for your time.

Not really. I believe the issue is elsewhere.

Can you turn on debugging, so that we get more info in the nsclient.log? I believe in the [/settings/logfile] section, you can set:
and restart the NSClient++ service. See if you are going to get some extra info in the log that can point us to the right direction.

Good morning,

In my nsclient.log appears all night:

I execute:

Whats is the problema??

Edit: And only fails in the evening.

Thanks for your time.

Is the box doing something really resource intensive "in the evening", like backups, etc?

Good morning,
The evening runs a backup in the windows machine.
Thanks

My suggestion is to upgrade to NSClient++ 4.x
