Now pulse daemon starts the lvs daemon which manages
the nanny daemons, which run port test scripts and
setup the routes per your lvs.cf.

You might also check the lvs daemon - see if it is
going Z (Zombie).  If it is, it will stop managing the
nanny daemons - though the nannies should keep
functioning as long as thy are running, even if they
are orphaned. 

Check with: 
             ps vafx
