intermittent failures when reuse_port is enabled
I'm encountering connection issues to Dovecot when reuse_port is activated.
Some of the connections work fine, but about every 3rd of them does not
receive the banner after the TCP connection has established:
# nc -v 10.6.7.133 143
Connection to 10.6.7.133 143 port [tcp/imap2] succeeded!

Linux SO_REUSEPORT
...how it works for people :) It's going to be in v2.2.6, which I'm planning on releasing tomorrow. Note especially the warning about the bug:
http://hg.dovecot.org/dovecot-2.2/rev/a991a0547daa
So the idea is that you'd do something like:
service imap-login {
inet_listener imap {
reuse_port = yes
}
process_min_avail = 4 # number of CPU cores
}
And the load should be distributed more evenly to the processes.

IMAP hibernate and scalability in general
...sses are still keeping the listener port open.
Huh, SO_REUSEPORT was already implemented in 2013. I completely forgot about that. Would be useful to try if it works better (or at least not worse) and maybe change it to be enabled by default in some version.
