E2Guardian stops

[ravegen]

I have latest version of e2guardian in pfsensebox. It is now working.
I noticed that if I unchecked the Watchdog option in Daemon Tab, e2guardian stops and dont restart. If I check the Watchdog option, if the e2guardian stops, it will restart ofcourse.

Now my real question is, why does e2guardian stops that there is that watchdog option on the daemon tab.
