Hmm. So .. Do you see anything different in log files around that time?
For example:

imap-login: Info: Maximum number of connections from user+IP exceeded
(mail_max_userip_connections): user=<tss>, method=PLAIN, rip=127.0.0.1,
lip=127.0.0.1, secured

or:

dovecot: Error: Maximum number of mail processes exceeded (see
max_mail_processes setting)

or anything else with "Error:" or "Fatal:" prefix?

I'd put these to different files. It's then easy to see if there have
been any errors, because only errors will be written to log_path.
