Richard Mudgett updated ASTERISK-26669:
---------------------------------------

    Attachment: jira_asterisk_26669_v13_test.patch

[^jira_asterisk_26669_v13_test.patch] - This patch updates some debug messages and records the serializer sending messages earlier where possible.  DNS resolution causes the outgoing serializer to not get recorded to handle responses.

What kind of addresses is DNS looking up? IPv4, IPv6, or both?

The last two crashes are reminiscent of ASTERISK-26344 where the tdata was destroyed early.  It's like the pjproject patches to fix that issue aren't being applied.  You can ensure that they get applied by doing the following:
{noformat}
cd third-party/pjproject/
make distclean
cd ../..
./configure --with-pjproject-bundled <- or whatever command you use to configure for bundled pjproject
{noformat}

> Hi guys,
> Been getting an intermittent segfault with asterisk 13.13.1 since we upgraded. Its a low-load server but happens maybe a few times a day. 
> We jumped a few versions from 13.10 so not sure if this is a last-release regression or not.
> We have another higher-load server (with the same setup) that has not yet crashed in the same way.
> I will attach backtraces; the fault its self comes from pj_atomic_dec_and_get from /usr/lib/libasteriskpj.so
