[Martin Tomec (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=237464#comment-237464 ] 

Martin Tomec commented on ASTERISK-27037:
-----------------------------------------

The workaround is not enougth, because the transaction is probably fully deleted. Today we had another segfault with obviously corrupted tsx:
{noformat}
(gdb) print  *((pjsip_transaction*) 0x7fdc180e24c8)
$9 = {pool = 0x7fdc0fc690a8, tsx_user = 0x7fdc0fc690a8,
  endpt = 0x6466377830676c64, terminating = 808989027, grp_lock = 0x38,
  mutex_b = 0x0,
...
{noformat}

> We were experiencing frequent asterisk crash in production enviroment. Maybe it was caused by some mallformed webrtc registration. For now we can´t reproduce the issue, so I send only backtrace from coredump. In logs I failed to find any common line for all crashes, only this is suspicious:
> {noformat}
> [Jun  7 12:10:55] ERROR[21634] res_pjsip.c: Error 171060 'Unsupported transport (PJSIP_EUNSUPTRANSPORT)' sending OPTIONS request to endpoint webrtc_kaplan
> {noformat}
> Please let mi know if I can get more from coredump or log
