Rusty Newton commented on ASTERISK-26307:
-----------------------------------------

Thanks for the logs Bill.

[~kharwell] took a look at the issue with me and he is curious to get:

* the pjsip configuration for the endpoint/s involved in the call flow where the crashes occur. 
* In addition the dialplan involved would be very helpful.

The issue may be occurring when the URI is cloned, but we are not sure what happens to get it into a funky state. We'll likely have to duplicate it, or get more data to find out. Understanding more about the call flow and how the endpoints are configured may help out.

If you can build a test system where you have the same call-flow and session expiry and it reproduces the problem.. that would really help. Likely the real trigger is more complicated, but you never know.

As it is right now, with the current data, we aren't sure that any further investigation will lead to root of the issue.

> 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.
