    Attachment: ASTERISK-28213-followup.diff

[~rossbeer] I believe some locking needed to be added to the original patch to make it more consistent. Give the [^ASTERISK-28213-followup.diff] patch a try and see if that helps.

Note, the follow up patch depends on the first patch, so the first patch needs to be applied first and then the followup one.

> A deadlock occurs on AOR removal when a transport has gone away, and a NOTIFY is being sent the endpoint. The AOR is blocked in mariadb and the second thread blocks on the first.
