hen listing TCP connections via lsof, there are only around 30 connections open to IMAP and we have exactly the same amount of dovecot/imap processes. These connections are held by 30 dovecot/imap-login processes.
The other 70 dovecot/imap-login processes seem to do nothing. They're all sitting in "epoll_wait(14," according to strace but don't have TCP connections open.
Have you tried reducing the number from 100 to, say, 30?
But as Aki said, doveconf -n is crucial, especially since you upgraded from an older version.
