Right. This is the main problem. So the question becomes why is the
connection being refused.

If that happens, there should be a log entry. You can grep process_limit
and client_limit from logs.

"Connection appears to be hanging, reconnecting"
I usually log errors to a different log file. Normally that file should
be empty, so you can easily see all the errors and warnings that could
be causing problems.
log_path = /var/log/dovecot-errors.log
info_log_path = /var/log/dovecot-info.log
