> After upgrading from Asterisk 16.8.0 to 17.3.0 we have been experiencing crashes during video conference calls. After some time with 2 or more participants in the conference asterisk crashes with a SIGABRT or SIGSEGV. The traceback looks different most of the time but seems to be memory related in all cases.
