Description of problem: There is a problem with dovecot's error log processing in fail2ban, which uses up CPU. And the fail2ban service is no longer responding. Version-Release number of selected component (if applicable): fail2ban-1.0.1-1.el9.noarch How reproducible: After enabling the dovecot feature of fail2ban, an invalid TLS connection is made. Steps to Reproduce: 1. Install and Setup RHEL9/EPEL 3. dnf install fail2ban dovecot 4. enable dovecot feature echo "[dovecot]" > /etc/fail2ban/jail.local echo "enabled = true" >> /etc/fail2ban/jail.local 5. systemctl restart dovecot fail2ban 6. echo QUIT | openssl s_client -connect localhost:imap -tls1 -starttls imap Actual results: fail2ban-server continues to use 100% of CPU Expected results: Processed without increased load Additional info: https://github.com/fail2ban/fail2ban/issues/3370
I can confirm the bug - I also got got full load and a no responsive fail2ban-server until I changed my config as in the fail2ban-bug-issue
I've seen the same issue on F36 and can say that the fix proposed in fail2ban-bug-issue works.
Upstream seemed to indicate the the fix would make it into a release fairly soon so I was trying to wait for that rather than having to update the package a second time for a version change only.
