There's a persistent Net-SNMP session connection established between
the master and subagent. This is used for all request/response
dialog between the two.
(Note that it's actually the subagent that establishes this session,
not the master agent. But I doubt that is relevant to your problem).
I'd agree with Mike - the first thing to do would be to identify whether
this is an issue between the master and subagent, or between the
master and your monitoring application.

That's not strictly true, Mike.
The AgentX protocol supports the idea of multiple sessions between
the same subagent/master pair. See RFC 2741, section 6.1:
h.sessionID
..... A subagent may establish multiple AgentX sessions
by sending multiple agentx-Open-PDUs to the master agent.
I haven't checked the Net-SNMP code, as to how this is implemented
(or even if it's supported at all). I strongly suspect it hasn't really
been tested in anger.
