Polling engine stops polling without providing any error

mdriskell over 11 years ago

I've been having sporadic issues with one of my polling engines. I'm running NPM 10.2.2 and on my primary engine polling seems to just stop even though all services are operational. I have gone through these steps from this KB but the issue keeps occurring.

http://knowledgebase.solarwinds.com/kb/questions/2517/Collector+Data+Processor+and+Collector+Polling+Controller+start+and+stop+intermittently

I'm not seeing any services stop but the poller just ceases collecting data. I'm opening a case with support and will reference this thread.

Can you post here your case number?
How big was collector SDF files before you reset them?
Thanks

I did it yesterday and don't remember the sizes.
As of right now the polling controller is around 200MB, the job tracker 75MB and the Job Engine V2 61 MB

Running diags now for support...as soon as I'm done I'm going to replace all the SDF files as this seems to get the system running again.

Also it seems that these problems started after I upgraded to SAM 5.01, IPAM 3.0 and installed SEUM 1.5 last week Monday.

We've seen a similar issue on one of our pollers as well. NPM 10.2.2, core 2011.2.2
We rebuilt the box thinking the OS was corrupted but the issue did not disappear with the rebuild.
A consistent symptom is that we can try to stop all services but the Job Engine v2 never finishes stopping. Reboot of the server is required.
One thing we've noticed is that the issue seems to occur anytime that OS patches are applied to the server but the server isn't rebooted.
We haven't opened a ticket on this. We figured we'd wait until we migrate to NPM 10.3 so we can skip the answers of "it's fixed in the next version".

JobEngine V2 will not stop using the service manager for me either. I had to kill the process using task manager before doing my repairs.

Really hate that the system censors my use of the word K .I .L. L

Hah! I think it made the post funnier when I inserted my favorite 4-letter word while reading.
Apparently not a unix-oriented vocabulary in the filters.

Pardon my interjection, but I would appreciate it if SolarWinds would produce an official white paper on this issue. The tendency of these SDF files to require periodic regeneration has been around a long time. I realize that there is a KB on the topic, but a white paper could also shed light on why this happens, and even how to predict it. Could those of us with SAM benefit from using FIle Size monitoring to keep an eye on how the SDF files grow and alert us when thy reach a dangerous size?
