Fail2ban logs getting huge

My fail2ban logs are getting ridiculously huge… like 16Gb ish…

looking at the logs, they are filled with:
2025-01-08 11:42:50,645 fail2ban.actions [539580]: HEAVY Actions: wait for pending tickets 2 (default 2)
2025-01-08 11:42:50,706 fail2ban.actions [539580]: HEAVY Actions: check-unban 20, bancnt 0, max: 20

Can someone help, if you have any idea what is going on?
