I haven't (yet) monitored any netapp devices with devmon (most likely I will 
soon) ... but there is a template, which has tests named 'cluster', 
'if_load','netapptemp','quota','status' and 'volume'. You may want to consider 
trying it instead of this script. If the teplate is missing something which is 
available by SNMP, we can add support for it.

BTW, are you running this out of cron, or from hobbitlaunch?

Well, then it seems SMF is a bit brain-dead ... however, you could run 
something equivalent to:
pkill -u xymon vmstat

as well, which on my test box results in no processes running as the xymon 
user (after stopping the service via the init script on a Linux box).

I don't think I've ever seen hobbitlaunch crash ...
