Hi,
I'm getting a deadlock every so often with asterisk 13 GIT. There are
a lot of low level locks:

Should an issue be created on Jira?

Hi Ross,
This may be the same issue that George discovered earlier today while
doing some testing. If you apply the code change on this review
https://gerrit.asterisk.org/#/c/4902/ , do you still see the issue?
