> Our Asterisk servers occasionally fail to hangup channels (IAX2 or SIP).
> We are running version: 13.8.2.
> The sympthoms are a follows:
> * We observer a HangupRequest event via AMI but the Hangup event does not occur.
> * One Asterisk thread starts consuming 100% CPU, i.e. burning one core.
> * Strange warning messages occur in CLI and log repeatedly every few seconds:
> ** IAX case:
> {noformat}
> WARNING[15982] chan_iax2.c: Max retries exceeded to host 10.101.1.5 on IAX2/125-5832 (type = 6, subclass = 11, ts=119996, seqno=24)
> {noformat}
> ** SIP case:
> {noformat}
> WARNING[21518]: chan_sip.c:4333 __sip_autodestruct: Autodestruct on dialog 'e8954fa42ffee2d1ace1ac4c6323d990 at 10.249.4.97' with owner SIP/999222-0000149c in place (Method: BYE). Rescheduling destruction for 10000 ms
> {noformat}
> * The channel stays alive (i.e. still visible via CLI, AMI status, ARI, etc).
> * The channel cannot be hungup (via CLI, AMI, etc).
> * The only fix is to restart Asterisk.
> Up to now, we where facing this problem three times:
> # IAX2 channel, thread {{bridge_channel_depart_thread}}
> # SIP channel, thread {{pbx_thread}}
> # SIP channel, thread {{pbx_thread}}, with thread debugging enabled (includes {{strace}} output).
> I've attached the debug info for each of the above cases.
> Maybe, this bug is related to:
> * ASTERISK-25911
> * ASTERISK-27538

> If I can image, that you need more detailed information to track down this bug.
> If so, please let me know how I can provide it and I will try to reproduce this problem.
