Hello.

Since I upgraded few months ago from version 1.0 to 1.1 (right now using v1.1.rc4) in logs for some users only (but in different servers) I noticed errors:

dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor dovecot: Fatal: IMAP(user3): write(event_pipe) failed: Bad file descriptor

So only for some imap users. And in different servers. And this error happens suddenly, I already tried to delete delete cache and index files. However the users themselves haven't noticed any problems.

Shall I just ignore these errors on what?

Configuration is quite simple:
