commit a4e89f57a8d733ea74df7b0de31eb977d6d37388
Author: Ronnie Sahlberg <[EMAIL PROTECTED]>
Date: Tue Jul 8 09:58:10 2008 +1000
update the monitor event for nfs to track how many times in a row it has
failed
to "ping" the local nfs daemon.
Once it has failed more than 3 times in a row it will attempt to restart
the nfs service.
