        Sometimes, in extremely rare edge cases, the Sofia SIP stack may stop
        responding. These options allow you to enable and control a watchdog
        on the Sofia SIP stack so that if it stops responding for the
        specified number of milliseconds, it will cause FreeSWITCH to crash
        immediately. This is useful if you run in an HA environment and
        need to ensure automated recovery from such a condition. Note that if
        your server is idle a lot, the watchdog may fire due to not receiving
        any SIP messages. Thus, if you expect your system to be idle, you
        should leave the watchdog disabled. It can be toggled on and off
        through the FreeSWITCH CLI either on an individual profile basis or
        globally for all profiles. So, if you run in an HA environment with a
        master and slave, you should use the CLI to make sure the watchdog is
        only enabled on the master.
        If such crash occurs, FreeSWITCH will dump core if allowed. The
        stacktrace will include function watchdog_triggered_abort().
