Hi, After what we thought was rigorous testing we put our new 3CX deployment into production use but on the first day it has segfaulted, dropping in-progress calls and needing services restarted. I have seen a few threads about the main 3CXPhoneSystem01.service segfaulting although the posts don't seem to contain any resolutions, so I figured I'd post this, and perhaps an admin would like a core dump for further analysis? Version: Build 15.5.6354.2 Platform: Debian 8.9 running on VMware Prior Activity: Seemed to be two incoming calls active at the time of the crash Syslog: Nov 27 11:05:59 3cx kernel: [6438872.495701] 3CXPhoneSystem: segfault at 1158 ip 00007f94dabdb590 sp 00007f94c6ffc038 error 4 in libresip-1.10.so[7f94daa69000+25a000] Nov 27 11:05:59 3cx systemd: 3CXPhoneSystem01.service: main process exited, code=killed, status=11/SEGV Nov 27 11:05:59 3cx systemd: Unit 3CXPhoneSystem01.service entered failed state.

There is a coredump at /var/lib/3cxpbx/core that I could send to an admin together with anything else needed. Let me know.
