Hello. I am new to ZM and I have encountered an issue. I am sometimes getting the following error messages in my logs. When I do, new events aren't being created on the monitor(s) in question.

For these errors, it seems like I can "fix" the problem by deleting the most recent event for the monitor. I have no idea if or what I am doing that would cause them to start happening.

Can somebody help me?

I've seen this when events were being deleted immediately after creation. Check your filters.

Any filter that deletes events or does much of anything should have an End Date/Time NOT NULL rule so that it only matches finished events.

Okay so I *thought* the only filters I had were the two that came with ZM. However I had a bunch of "_TMP" filters and a few of them were set to run in the background. I deleted all of these. So let's see what happens now.

Thanks!

I had the same error, but no additional filters to PurgeWhenFull and Update DiskSpace, which puzzled me a lot.
Then I noticed that (due to another process logging extensively on the same partition) my Diskspace was at 80%, which triggered the PurgeWhenFull filter during an event, creating such parent/child database errors.
Cleaning up my partition solved the issue...

I had the same problem and I could fix it following your suggest. THANKS !!
