snmpd threshold value

All,

I am probably just overlooking something stupid but here is my question:

I have a system running Solaris 8.
System has Helix Internet Server (Latest version of RealServer).
We did have the version before the latest installed but were running into a
memory leak that caused once the system ran below 150MB of free memory it
wouldn't serve any more streams.
The ChangeLog for the latest Helix Server said there was a memory leak that
was fixed in the latest release. (Sounds like the answers to our prayers).
This didn't work (go figure).
We monitor using mon the SNMP value of AVAIL MEMORY on these systems.
When the memory <150MB it pages us so we can reboot it.

Can we automate this? Through monitoring?

Isn't there some way to put this into the snmpd.conf to monitor threshold of
minimum of 150MB. If this is reached trigger another value in snmpd.conf that
tells how to fix this problem? (ie. reboot)
Also I would like an email sent out to tell that the machine is being rebooted
by SNMPD.

Now just incase is there a way to make sure that it doesn't continue to go
into an infinite loop and if happens more then 1x in 24 hours then don't do
anything and Page will go out(from our existing system that already monitors
this value)?

Cheers, Chris
