Daniel Journo commented on ASTERISK-26836:
------------------------------------------

I've just done a test and using AMI, I send the 'pjsip reload' command 5 times at once. 
Asterisk was able to deal with it without any problems.

I then did it again, and at the same time submitted a 'pjsip reload' from the CLI was got this output.
A module reload request is already in progress; please be patient

    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet
    -- The previous reload command didn't finish yet

So the memory corruption doesn't appear to be related to multiple reloads at the same time.

> This is a recurring issue on all my production servers. When it happens, Asterisk stops serving SIP clients properly.
> It reads to me as a memory leak as it's just one character incrementing.
> The latest time, it occurred shortly (but not immediately) after I issued a 'pjsip reload', but it may have just been a coincidence. I've included the timing in the CLI log.
> Seems to happen every 4 or 5 days requiring a 'killall -9 asterisk' and 'database deltree registrar' in order to get working again. I can't remember, but the first time it happened, Asterisk would not respond to 'core stop now' or 'core restart now' so I had to do killall. But I havent tried 'core stop now' during subsequent issues.
> This issue stops all endpoints from communicating with Asterisk. Even ones that have already registered.
