             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_confbridge, Resources/res_pjsip
    Affects Versions: 17.3.0
         Environment: Debian Buster (10.3)

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.
