Rusty Newton commented on ASTERISK-26768:
-----------------------------------------

That is good to hear. I'm going to open this up since you have a good trace. However you may want to see if you can gather additional or more extensive logs, preferably with the DEBUG log level on and both verbose and debug turned up to 5 or above.

Remember that chan_sip is under extended support (no longer supported by the core dev team directly) since Asterisk 12, so the time until resolution will reflect that.

If you can reproduce a similar issue using PJSIP, a fix would happen quicker there since that is where SIP development is focused.

> Hi,
> We have between one and two crashes by day on Asterisk when we use chan_sip with more than 90 devices with TCP mode.
> We didn't arrive to reproduce the bug, however, I've discussed with Matt Jordan today at FOSDEM who told me to open an issue with the all information I have.
> This is an extract of the Asterisk logs and the backtrace.
> It's my first backtrace capture, I hope it will be enough to help you.
> If necessary, I've also a SIP pcap capture but I can't share on the Web.
> Have a nice week.
