[Dovecot] odd epoll() errors

Try to run  'cat /proc/sys/fs/epoll/max_user_instances' .  It will
propablly
print  128  which is default on recent kernels. You need to raise to say
1024 using  'echo 1204 > /proc/sys/fs/epoll/max_user_instances' or
via
sysctl.

I finally figured this out. You need to
increase /proc/sys/fs/epoll/max_user_instances. I'll improve the error
message and add checks to Dovecot startup to warn if it's too low.
