Description
While testing at the SDC plug-fest, found the smbd authentication service stopped (after an "authentication flood" test).
No thread remains doing listen/accept on the authsvc socket.

The system log shows that the "auth flood" client managed to (temporarily) run us short of memory, so attempts to create a new authentication context failed, and then the accept loop terminated. We should not terminate the accept loop in that case.

I'm not exactly sure how to reproduce this failure. It happened with a stress test we don't have.
We verified the fix at the SDC 2019 plug-fest.
