SSL connection reset by peer

[Vince42]

Hi,

I am running a dovecot server and have set up an external monitoring,
where every five minutes a login with SSL on port 993 is done. I usually
get once a day an error "connection reset by peer - SSL connect", which
goes away until the next monitor is executed.

Initially I thought that raising the mail_max_userip_connections in
protocol imap in 20-imap.conf to 256 should do the trick - but the error
stays.

What could be the reason for this error and which configuration values
could be changed in order to avoid this error?

I read a lot of different suggestions - but did not find a plausible
explanation and recommendation.

Thanks in advance!
