[asterisk-bugs] [JIRA] (ASTERISK-21996) chan_iax2 fails to process network packets after a while

Heiko Wundram commented on ASTERISK-21996:
------------------------------------------

I've now had 11.5.0 running for quite some time, and initially, I though that the issue was fixed, but that doesn't seem to be the case. It has now resurfaced twice (i.e., IAX network packets simply stopping) in a row. I'm currently setting up Asterisk to be able to get the requested logs, and will get back then.

> After a while, chan_iax2 fails to accept new networking packets. The initial symptom is visible when enabling IAX2-debugging: outgoing packets are shown, but all incoming packets (directed to the correct port) are no longer visible inside Asterisk, even tough they do show up with an appropriate tcpdump on the corresponding network interface they arrive at. All IAX2 peers become unreachable, and IAX2 calls stop working.
> I've core-dumped a running Asterisk executable while it was in this state, and it seems that the IAX2 networking thread (chan_iax2.c:network_thread) isn't running anymore. The issue doesn't seem to affect any other areas of networking/SIP telephony in the Asterisk core, and the IAX2 module seems to be running fine otherwise (i.e., all threads are "idle") even though the networking thread is "gone".
> I've not yet tried additional debugging while Asterisk is running yet.
