Message #1098

Is that the only thing in the log? (if so enable debug logging and post full (or more detailed) log)

Thanks for your assistance. Here is what is in the log when it stops sending.

I have uploaded a new nightly build which adds some more logging as well as catches around the NSCA thread so feel free to see if this sheds more light on the problem.

    Used the build and got the exact same message as noted above. Ran fine for about 19 hours and then stopped.

      Pulled down the 0.3.6-RC7. Process ran fine for 5 hours exactly. Then just stopped. No errors noted it just quit running. If I stop and restart the process it will continue to run fine and then quit after an undetermined amount of time.

        do you always get the same "sahred session" message in your log?

        Prior to the RC7 version I did when it failed that would be the last entry. Before failing the "shared session" is not listed in the log. After moving to the RC7 release it just stops and requires a restart of the service. Here is the last entry in the log when it stopped last. There does not seem to be a pattern in the time frame that it stops. Also the service shows that it is running but the process does not consume and CPU time. When it is functioning properly I see it use CPU time in the task manager.

        Did some further investigation. Every time this stops working there is an error in event viewer:
        
        TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts. M$ as a limit on vista ultimate of 25 connection. There are methods to get around this but would rather not.
        
        I have it set to send out every 5 seconds and using encryption.
        
        I turned it down to every 30 seconds and will see if the error returns.
        
        Regards,

Message #1138

I have this same problem on multiple Win 2003 servers. I am only using passive checks on hosts, and they randomly just stop sending. I changed debug=1 on few servers, and I get this error message in log: cpp:736: No shared session: ignoring change event! , but only after I remote desktop to the server, before that nothing for like two days.

When I restart the nsclientpp service everything starts to run normally. It can run 2 hours or 2 weeks just fine, and then stop again.

Should I try the RC8 version?

  No help with RC8 version. At this moment I have about 20 of 30 servers not sending results.
  
  No errors in windows event logs or nagios server logs. nsclient++ log has last lines: 2009-04-08 16:40:37: debug:modules\NSCAAgent\NSCAThread.cpp:182: Sending to server... 2009-04-08 16:40:37: debug:modules\NSCAAgent\NSCAThread.cpp:189: Looked up 192.168.xxx.xxx to 192.168.xxx.xxx
  
  And when I log on to the server to see what's going on, it logged these two lines:
  
  2009-04-14 11:26:00: debug:NSClient++.cpp:745: No shared session: ignoring change event! 2009-04-14 11:26:01: debug:NSClient++.cpp:745: No shared session: ignoring change event!
  
  If I restart nsclientpp everything runs fine again for some time...

  I installed RC8 on about 10 servers, and I'll keep you informed

    Hello,
    
    I have your some problem, I tryed also the rc8 but nothing to do.. I am experiment nagios in my farm, I have more then 100 windows machine and about 900 linux servers. For this reason I would like to use nsca instead nrpe. Nsca for linux servers work fine but for the windows servers, with nsclientpp (i tryed rc2 and rc8), after a while I didn't receive the passive checks anymore. For this reason today I switched to NRPE for the win servers.
    
    Please if you found a solution, write it here.
    
    Thank you --
