Since I upgraded to the Windows 2.2.0 Zenpack, I have been getting frequent Zenpython daemon crashes. Data collection/graphing will stop and I have to start the daemon back up. It happens every 3-4 days.

I'm seeing the following error in the Zenpython log, it happens roughly around the same time that graphing stops.

[Errno 12] Cannot allocate memory => you have a problem with a memory. Analyze memory usage per process on your Zenoss server and then you should to see who is responsible for your problems.

Devops Monitoring Expert advice: Dockerize/automate/monitor all the things.

Thanks, I will look into the per process memory usage.

It is interesting to note that the entire zenoss server is only using around 50% of the available ram (50% is not used, buffered, or cached). Something must be artificially limiting processes from grabbing more memory.

I too upgraded my Microsoft Pack to 2.2.0 and have been experiencing the same crashes and graphs stop graphing. The WMI collectors work just fine. I blame the software, because it started to fail after the update.
