No problem, ... It is easy to miss details in individual messages when
trying to keep up with a busy list. If the OP returns to this thread, we
may find out whether the remote issue was overly-aggressive concurrency
on the sending side, overly aggressive rate limits on the receiving side
or indeed excessive remote laod due to dictionary attacks, ... Observations
here confirm high per-message latency, but not connection failures, so the
best initial guess is remote rate/connection count limiting.
