Re: [OpenSIPS-Users] Opensips 2.2.3 crash on async.

Thu, 13 Apr 2017 04:29:03 -0700

The async(), as based on transactions, works only for requests, not for replies. This is limitation that will be changed in the next releases (but not in 2.3).
What you could do in 2.3 is to use launch() statement to run your async stuff. 
launch( blocking_function(...) );
The launch will start your function in background and continue your script.

Hi Bogdan,
Yes i have to do some accounting calls based on reply recieved. So i guess that means that async is not available in reply route? Is it still planned for future release or maybe in 2.3?

    Hi Qasim,

    This looks very very similar to an old report:
    http://lists.opensips.org/pipermail/users/2017-January/036231.html
    <http://lists.opensips.org/pipermail/users/2017-January/036231.html>

    And this was fixed in 2.2:

<https://github.com/OpenSIPS/opensips/commit/4023a5d797960d245b52eb73dc9fc26b8cdf2914>

    I guess you try to do some async stuff in the reply route, right ?

        Hi,
        I have upgraded my script from 1.11 to 2.2.3 which works
        fine until i put async function on a single rest_get query.
        When the async line is executed i get following errors:

            2017-04-13T14:03:45.320300+05:00 sip01 kernel:

        I also have a core dump available, after opening in gdb i
        get the following info:

            [Thread debugging using libthread_db enabled] Using host
            libthread_db library "/lib64/libthread_db.so.1". Core

            data=1) at context.c:173
            173             ((int *)ctx)[pos] = data;

        Please note i will keep core dumps if you guys need some
        more info on it.
