a decent number of crashes were found and fixed between 1.6.17 and the newest release 1.6.19.  I’d recommend moving to the latest release before you do anything else.

Dear all,

My Freeswitch crash after ending call.
I don't see any thing on log file, only one log crash on syslog:
Jul 20 16:15:07 kazoo kernel: [3052190.684540] freeswitch[31078]: segfault at 6270 ip 00007f7f76a5da55 sp 00007f7f4e003bd0 error 4 in libfreeswitch.so.1.0.0[7f7f769ee000+419000]

I also attached file core dump, but I don't understand what it show.
My Freeswitch version: FreeSWITCH Version 1.6.17+git~20170525T170320Z~efbf7e5473~64bit (git efbf7e5 2017-05-25 17:03:20Z 64bit)

You have any idea ?
