Samba service seems to keep regularly crashing.

Hi I'm using smb.service with Arch as part of a Time Machine backup plan. The smb.service will run for a few days but then seems to crash.  Here is the log:

Anyway to debug this?? It's quite annoying.
Samba Version 4.13.0

Re: Samba service seems to keep regularly crashing.

Do you have separate log file or use systemd to log all? either case what happened before crash would be interesting to see, e.g: user login etc.

Re: Samba service seems to keep regularly crashing.

Arch isn't going to help you with this, it is a Samba problem, Samba shouldn't crash.

Can you please go here: https://lists.samba.org/mailman/listinfo/samba
Register for an account and then post there, supplying as much details as possible, your smb.conf, more of your logs etc
