Version 2.1.16 logs the following error:
Apr 16 18:07:58 10.129.3.249 dovecot: stats: Error: Mail server input error:
UPDATE-SESSION [email protected] pop3: stats shrank: mlpath 1 < 2
Apr 16 18:46:44 10.129.3.233 dovecot: stats: Error: Mail server input error:
UPDATE-SESSION [email protected] pop3: stats shrank: mlpath 3 < 4
Were there any reasons NOT to apply stats.diff the 2.1.x branch or did you
simply overlook my mail?
Regards
Daniel
