I've researched this problem a number of times, usually I see suggestions to increase ulimit.
I've done this a number of times, all the way up to:
ulimit -n 8192
I've put that in the init script right above the daemon start line.
What exactly is the "daemon start line"
I'm sorry, I forgot to specify that I was using Debian Linux:
case "$1" in start) if grep protocols /etc/dovecot/dovecot.conf | sed 's/#.*$//' | tr -d '"' |
egrep -q '[^#]*(\bpop3s?\b|\bimaps?\b)'; then if [ -x /usr/lib/dovecot/imap-login -a -x /usr/lib/dovecot/imap ]

Many Linux distros override ulimit in their internal scripts. If you're using Linux, you could check if dovecot process really has 8192 limit:
cat /proc/
pidof dovecot/limits | grep 'Max open'I've seen this suggestion on the web a few times, but there's no such directory, /proc/
pidof dovecot/limits or /proc/*/limits for that matterpidof dovecot
shows the pid for:
/usr/sbin/dovecot
I've tried "grep -i max" and grep -i open in the /proc/$pid/* directory for every pid of every dovecot process on the system, none of the files in there contain either word.

JW
You could try: /etc/security/limits.conf
your_dovecot_user soft nofile 524288 your_dovecot_user hard nofile 524288
Not sure if instead of your_dovecot_user, you should increase the limits for the root user .... ??
