------------------------------------------

[~billbrigden] Thanks for the information.

    I can disable SIP UPDATES's mid call?
{quote}
Someone else can correct me if I am wrong, but I don't think that is possible to do mid call.

    Which timer is causing the SIP UPDATE to trigger (ie. to decrease it so make it easier to reproduce)?
{quote}
I think your session timers guess is a good one. Try lowering the _timers_sess_expires_ value and see if it still crashes or crashes earlier.

    Any other pointers to duplicate easily?

Not really sure about other things to try to make it crash, but you could try a couple of things to see if it doesn't crash. For instance, try setting _send_pai_ and/or _send_rpid_ equal to no for the endpoint in question.

You said it was random, but do you know if it happens on the same endpoint each time of different ones? If the same it'd be worth comparing the differences between endpoints. Also looking at the debug log it appears it is missing some expected debug. If the debug level was previously set below 5 would it be possible to try to capture it again with debug set higher?

> Will attach BT (both normal and full). Oddly, I have compiled with: DONT_OPTIMIZE, DEBUG_THREADS, BETTER_BACKTRACES however it shows that some values are optimized out.
