The Scotty process (under Unix) is starting up nmtrapd (if not yet
running) and connects to it in order to actually receive traps. So the
error message comes from an attempt to reuse a transport endpoint
which the OS does believe is still in use. To say more, we need much
more details about what is happening (e.g. strace output from those
processes that are involved).

No. Errors that happen while reading or writing MIB objects are
signalled in the response PDU. A trap indicates that some asynchronous
event has happened on the agent.
