Red errors in log during parity rebuild

[Helmonder]

My log shows a large amount of the following error lines yesterday:

The errors were not there before the 19th and are not here after 19th, system has not been rebooted.

 

The erros appeared yesterday during the time that a parity rebuild was running (due to me removing a couple of old drives out of the array). System appears to be functioning fine at the moment.

 

Diagnostics are attached.
