Hi,
after update to Dovecot 2.1.5 (Ubuntu 12.04, dovecot from https://launchpad.net/~kokelnet/+archive/dovecot21) we are getting a huge ;-) bunch of log entries about " imap(USERNAME): Warning: Inotify instance limit for user 5000 (UID vmail)".
At last I did an echo 512 > /proc/sys/fs/inotify/max_user_instances
but the logentries did appear again after some minutes.
Make it higher. Each imap process that is in IDLE needs to have an inotify instance. So with the above you can have max. 512 IDLEing IMAP processes before you get the error.
