[asterisk-bugs] [JIRA] (ASTERISK-29286) chan_pjsip: Deadlock between sending response and transaction layer

[Kevin Harwell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=253909#comment-253909 ] 

Kevin Harwell commented on ASTERISK-29286:
------------------------------------------

Are you comfortable with using {{gdb}}? If so could you load asterisk and the core file:
{noformat}
$ gdb asterisk /path/to/core
{noformat}
And then within {{gdb}} execute the following commands and comment back with the output:
{noformat}
(gdb) p *tdata->msg
(gdb) p *inv
(gdb) p *inv->invite_tsx
(gdb) p *inv->invite_tsx->cseq
(gdb) p *cseq
(gdb) p *cseq->cseq
{noformat}
(hopefully typed those correctly)
