[Dovecot] pop3-login: Fatal: io_loop_handle_add: epoll_ctl(1, 5):

[Victor Benincasa]

I'm having this same issue in one of my servers since I updated my Dovecot 
from 1.2.4 to 1.2.5. The problem still with 1.2.6 too.

I cannot find what is triggering the problem, but it happens aleatory and I 
need to restart the dovecot daemon to make the service run properly.

My info:

Something else I can help? Or additional information that I can provide?
