I thought an individual smbd got spawned for each connection, and then setuid to the user who was connecting. Perhaps I’m wrong, or out of date.
My next suggestion would be to dig in and figure out how to increase logging verbosity. make sure that /var/log/samba is mode 1777 so if i’m right about the suid bit, each individual smbd will still be able to write there.
