Subject: [PATCH 21/39] MONITOR: Do not set up watchdog for monitor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It makes little sense to set up watchdog for monitor because there is no
entity that would restart the monitor. Therefore we should disable the
watchdog for monitor process.
