Hello again,
I might have more informations about the matter. I modified dovecot's
configuration file so that when calling imap-login it will call it
through strace.
From what I could understand (I'm not really confident with that output
yet ;-)), it seems that epoll_ctl are not blocked as one could occur
before the failing one.
I attached a text file with the strace output as copying it in an email would be awful to read with the 80 characters limit.
Hope this help better understand the problem.
Thanks !
