We have a very modest system with about 1000 users, 5 pop3 logins per
second, a few concurrent imap logins from the webmail system.

Using DB3.2, we NEVER had any problem whatsoever. no lockers, no hangs,

I am not switching the Debian Cyrus packages to DB4 until I am forced to do
so :)  too many nightmare stories for my tastes.
