What is your cycle time? Is it 30 sec? If it is, try increasing it to 1
minute.

As I mentioned in an earlier e-mail, I'm trying to get monit to watch
a group of processes so it can start/stop ospfd for an anycast high
availability application. However, in doing this I'm seeing some odd
behaviour that doesn't match what I expect -- is this a bug?
In the scenario below, why is it ever trying to start ospfd? If apache
is down, shouldn't ospfd stay down until apache comes back up or is
monitored again after being unmonitored? It does end up in the correct
state at the end, but not without restarting and stopping ospfd twice
in the meantime.
As an example, I have the following configured:
check process apache with pidfile /var/run/httpd.pid
start program = "/etc/init.d/httpd start"
stop program = "/etc/init.d/httpd stop"
if failed host localhost port 80 protocol http
and request "/" then restart
if 2 restarts within 2 cycles then stop
check process ospfd with pidfile /var/run/quagga/ospfd.pid
start program = "/etc/init.d/ospfd start"
stop program = "/etc/init.d/ospfd stop"
depends on apache
If I make it so that apache cannot run (by removing execute
permissions on /usr/sbin/httpd) and then kill it, I see the following
in the monit logs:
