Problems with ram usage on Windows 7 SP1 Remote Probe



Used-Case: Windows 7 SP1 Remote Probe with Dual-Core CPU and 4 GB-Ram and Windows Server 2008 R2 SP1 with Quad-Core CPU and 6 GB-Ram.

Within 5 days we’ve got a RAM-Lost of at least 1 GB, falling strong. Every, i think 10-12 days, we’ve got problems with our monitoring on the remote probe. It stucks and produce wrong errors which we don’t need ;).

The Probe with the problem got a lot of linux ssh sensors. Maybe this is useful.

nsi ram windows-7

We’ve solved the problem. Following this in a test-case.

  1. Check the processes in process manager
  2. Read the services which one hast he highest rate
  3. Re-check in system used process manager
  4. Restarting one network port
  5. Check if the error ist away

Following this we can say, that the NSI-Service got problems by closing the ports and recycle the ram. Restarting the port clears the cache on the NSI-Service. Furthermore the Paessler client crashed shortly before.

In case oft the NSI-Service, microsoft got some problems on Windows 7 SP1 which you can fix with this to packages.



Microsoft say’s you can use the Fix also to Windows Server 2008 R2 SP1.

Furthermore you can restart your Probe every week automatically with the PRTG Remote Manager. This will help the system to recycle the used ram.

We’ve test it for about 5 weeks and this seems to be the fix for us.

Thanks ;)
