Jordan McQuown commented on ASTERISK-20727:
-------------------------------------------

I'm on pbx purple - 1.7.5.6 - i've been updating from source to the current version since certified asterisk was released. Along with that updating the res_digium_phone version.

I've also manually updated to freepbx 2.10. However we do not use the digium supplied provisioning module as it had limitations so we wrote our own provisioning script. We have 12 digium phones registered to the system using the DPMA module. 

The hardware is a whitebox supermicro server
DPM module - 1.8.11_1.3.0 downloaded from asterisk.org


I'm not real sure what to say except I cannot reproduce the behavior without res_digium_phones being reloaded. We did not have this issue prior to installing certified-asterisk-1.8cert5 It seems to trigger more frequently when doing a digium_phones reconfigure all and then core reload.

> When freepbx issues a core reload or a manual core reload is issued asterisk crashes with "segfault at 0000000000000150 rip 0000000000483b50 rsp 0000000045f97d90 error 4" or similiar. I cannot reproduce when res_digium_phone.so is unloaded. I've tried debugging using methods described including valgrind. However I could not get the module to load when I recompiled with DONT_OPTIMIZE, DEBUG_THREADS, MALLOC_DEBUG.
