Can't remove temp file - should I be worried?

Started seeing lots of these messages this morning:
can’t remove temp file: remove /mnt/remotes/i5_750/kopia/pe8/09d/68685a1f1474aaafe2b8e5adc09-s56eaea7da1c0fc0b103.f.tmp.f675d9bfa5bdbade: no such file or directory

Should I be worried?

Thanks!

At this point - I stopped the snapshot. Will reboot both the client on which the repo sits + will reboot the client trying to snapshot and see if this fixes it.

Wild guess - are you out of disk space?

Nope plenty of space… I ended up rebooting both the client and the repository and it worked. I wonder if just disconnecting from the repository on the problematic client would have worked. In any case, this was the first time I saw such errors.

I tested restore for that file, sha256sum matches both at the source (linux) and destination (windows) so I think I am good.

Is it a best practice to keep Kopia UI “connected” to the repository at all times (i.e. I have three windows clients with Kopia UI backing up to a single repository on a Windows Server box). I also have a linux client backing up to the same repository… perhaps the problem was that it needed to be reconnected?
