I have been running Dovecot 1.2.5 since Sept 14. Beginning at about
03:28 on Sept 21 for no apparent (to me) reason and continuing through
the present, I am seeing log messages like the following and am
experiencing delays logging in.
Same problem here, after about the same time from last server re start.
Last restart log is:
Sep 14 19:05:07 server dovecot: Dovecot v1.2.5 starting up (core dumps
disabled)
First failure is:
Sep 23 06:26:14 server dovecot: pop3-login: Fatal: io_loop_handle_add:
epoll_ctl(1, 5): Operation not permitted
After the attached piece of log, the mail log is full of the same
failure, and no customer can login using pop3 (imap works with no problems)
After a server restart the problem was vanished.
May be there is some kind of resource leakage.
