[Dovecot] Dovecot service not responding after about a week of uptime
Hello,
The issue of dovecot becoming unresponsive happened again but after
several weeks instead of just one as before. As advised before I tried
to login through the IMAP port. Entering an incorrect password gets
rejected right away. Entering a correct password just hangs indefinitely.
Attached are a file with the IMAPS exchange and corresponding lines in
logs and another file with the output of ps aux.
Thanks in advance.

[Dovecot] Dovecot service not responding after about a week of uptime
Hello, The issue of dovecot becoming unresponsive happened again but after 16 days instead of just 7 as before. $uptime 09:53:01 up 16 days, 20:23, 1 user, load average: 1.32, 1.01, 0.83 As advised before I tried to login through the IMAP port. Entering an incorrect password gets rejected right away. Entering a correct password just hangs indefinitely. $openssl s_client -connect mail.pupat-ghestem.net:993 -quiet depth=0 CN = mail.pupat-ghestem.net verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 CN = mail.pupat-ghestem.net verify error:num=27:certificate not trusted verify return:1 depth=0 CN = mail.pupat-ghestem.net verify error:num=21:unable to verify the first certificate verify return:1 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a1 LOGIN wrongUser wrongPassword a1 NO [AUTHENTICATIONFAILED] Authentication failed. a2 LOGIN goodUser goodPassword [HANGS] Jan 15 09:58:58 hebus dovecot: imap-login: Login: user=<goodUser>, method=PLAIN, rip=192.168.173.254, lip=192.168.173.2, mpid=29852, TLS, session=<dIO0g/7vQQDAqK3+> After a restart of dovecot everything works fine: systemctl restart dovecot.service Thanks in advance.
