So oom-killer doesn't solve the issue? Then it's likely it has nothing  
to do with pop3-login, OOM killer just selects a bad target to kill  
(and Dovecot happily restarts a new pop3-login process) while the real  
memory-eating process stays alive. Can you check with ps what  
process(es) are eating all the memory?
