>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: PBX/pbx_ael
>    Affects Versions: GIT, 16.15.1, 17.9.3, 18.6.0
>            Reporter: Mark Murawski
>            Assignee: Mark Murawski

> Requirements for reproduction of bug:
> - Have a 'decent amount' of ael.  In this case, I have 650 lines of AEL in variety of files.
> Obviously not a 'normal' use case to issue 10 reloads at once, but when multiple scripts/systems might be asking Asterisk to reload at the same time, this could be triggered.
> 5 to 10 reloads should do it!
> {code}
> vbox-markm-x64 {/etc/asterisk/ael} root# for i in `seq 1 10`; do asterisk -rx "ael reload" &  done
> [1] 12335
> [2] 12336
> [3] 12337
> [4] 12338
> [5] 12339
> [6] 12340
> [7] 12341
> [8] 12342
> [9] 12343
> [10] 12344
> vbox-markm-x64 {/etc/asterisk/ael} root# asterisk -rx "core show locks" | grep "Thread ID" | wc -l
> 12
> {code}
> Depending what else is running at the time (perhaps pjsip adding hints to dialplan).  This will escallate quickly and lead to a very locked up Asterisk
> The fix is to address the missing reload mutex in pbx_ael.
