I found that the actual time or delay is 10 seconds. What I have determined is if the subagent delays for 10 seconds during a get operation net-snmp closes it's pipe and the subagent program receives signal SIGPIPE, Broken pipe.
I added a SIGPIPE handler to the subagent to prevent it from being terminated. And the master-agent-subagent reconnect after a period of time. Is this expected behavior from net-snmp. I am running in a system that could have 10 second delays - so there is not much I can do about this aspect of the problem. Any info you have on this would be appreciated.

How does the master agent shut your subagent down? I know of no protocol operation for this. Do you mean, perhaps, that your subagent is crashing because it expects the master to still be waiting after two minutes? SNMP operations are expected to be timely. Te exact meaning of "timely" is debatable, but two minutes, i.e. four times the standard timeout period is not debatable - it is highly untimely. I would suggest you use three objects: trigger, state, and value. The trigger can be set-only, and starts the operation. The status has values for "uncalculated" (initial value only), "calculating", and "done". The value is the result of the calculation or a default value. > Is there a way to tell the master agent to pause? There shouldn't be. Other folk want their info, too.
