OS is CentOS 6, dovecot-2.0.9-19
Just started using this server as a replacement for an old Debian server
running an old dovecot. The number of dovecot processes just grows and
grows until there are 100 concurrent login processes (we have maybe 40
or 50 users), and then nobody can log in any more. A reload resets, but
the number of stuck processes climbs very quickly.
Switch to "High-performance mode" [...] It works by using a number of
long running login processes [...]
