Did you notice anything different when this error appeared?
Is it a one time thing or does this happen often?

[bobhenl]

multiple times

not really sure if there's anything different but the other ones look a bit different, let me send you them

It shows more information only on that first error, then with others in the same day it's just the shorten one I've sent @Jumper251

basicalyl the first one mentioned in this message is appearing mostly in these logs when it's the first error in that day

This was already addressed, or @Jumper251 (both of these?)? as you mentioned in release you looked at concurrency issues?

[Jumper251]

I was not able to reproduce these issues but I made some changes to concurrency handling given your error messages. The latest update will hopefully fix these issues.
