Server daemon crashes; Last error: 27

I’m seeing server crashes consistently at the end of backing up a particular server.
UrBackup’s log shows this:

I’m seeing this from dmesg:

Thank you,

errno 27 = file too large for the file system.

Please also follow https://urbackup.atlassian.net/wiki/spaces/US/pages/8323075/Debugging+with+gdb+on+Linux if possible.

Thank you.

I hadn’t realize CephFS has a maximum file size, now I know. Increasing that limit should resolve the problem.

Thank you,
