Does these problems occure all the time, e.g. if you restart the Dovecot demon and there are just a bunch of users on it.
After restart - it work for some time, but it is just because no all connect to it again.
Do you have a file descriptor limit for the demon process?
System limit? 512mb. It not run on this.
Do you have some "security" stuff running, a BSD-equivalent of SELinux or AppArmour?
Nope.
As I sad before - i just increase *all* thing what can be a bottleneck twice. And seems to "fix" it. But it makes me think what it is real will be good if dovecot can say in debuging loging what he reach some limits from his config. It will make finding a bottleneck such easy.. heh. I just what to know - were was a problem, but seam to i don`t have any tool for this.
Any way - dovecot is a great and i glad what i migrate from a Cyrus. ;-)
