By default, net-snmp uses unix domain sockets for AgentX connections. This
means that the normal per process file descriptor limits will come into play.
However, you can run AgentX over UDP to get around that limitation.
(Restricting a UDP AgentX listening port to the localhost is strongly
recommended).

As far as the master agent is concerned, I believe AgentX registrations look
like any other registration, and there is no appreciable overhead. However,
I've never heard of anyone using more than a handful of subagents, so there may
be an issue lurking that nobody's hit yet.

You are lost in a twisty maze of little standards, all different.
