Weekly rsync backup produces "resource limit succeeded" monitoring alert

Hello,

I'm curious about the "resource limit succeeded" alert that pops up everytime my machine does a scheduled rsync backup.

Here are a couple examples of typical alerts:

Description: loadavg (1min) check succeeded [current loadavg (1min) = 15.2]

Description: loadavg (5min) check succeeded [current loadavg (5min) = 7.6]

The PC I'm using for OMV is fairly old - i7-6700K, 16 GB - but still pretty beefy for the task I would imagine. It's a weekly backup to an external USB HDD array.

Is this something to worry about?

Here are the load average graphs:

Great, that's a relief to hear. Thank you.
