[Samba] Smb daemon on Arch Linux dies after running for about 7-10 days - `SAMBA_4.13.4' not found

[Kevin Hilton]

Compared to most the posts on this lists, I have a smbd setup on an Arch Linux install used for home use acting in conjunction for a Time Machine backup solution for users around the household. The smb daemon will run for about 7-10 days before not being reachable but the MacOS time machine clients.

Logs from the Arch linux server for the smb daemon reveal the following:

My smb daemon version is:

If I restart the service, the smb daemon will again accept connections — for about 7-10 days prior to the daemon then then failing to log the streams_xattr.so module.  Is this a smb problem or more of an Arch implementation problem? How further to debug?
