My server throws this warning every 10 seconds, what does it mean and how can I fix it?:

[15:09:20 WARN]: [Essentials] Task # 55972 for Essentials v2.17.2.0 generated an exception

This is probably a mistake in essentails. A heartbeat is a virtual heartbeat which is executed every 10 seconds, for example.

Possibly. Download the new version or inform the developer about it.

Delete the plugin essentialsXMPP, that is superfluous, then the error message stops.

Thanks for the info. Installed with the complete package. What exactly does the plugin do?

I don't know, I never installed it because it seemed useless
