I have the same problem.The temporal fix is stop the dovecot service or the xinetd if it is runningunder xinetd. I have made a script that check if the number of dovecotprocesses are above 28 so, they stop the service, keep checking and  whenthe service is  below 9, start the service again. (DO NOT kill the processe=sor a reboot will be needed)the service stops about 50 times at day, due my cpu load and number ofusers.The bad news guys is that it has no solution!!!!I ve been seeking for months and nothing in internet is really usefull forthat. (if i am wrong, please tell me).After many and many analysis I ' ve figured out that it´s associated withthe low capacity of BQ to process the users authentification and when thereare many request at the same time, it just stop the authentification proces=sand the dovecot  go mad!I have made many test and observations, if someone want to talk about, mailme, or skype me.Tks2006/10/18, Christian Lappin <clappin (at mark) axsne.com>:>>>> Gerald ->> Yes in fact the server has been rebooted several times due to the fact it> will hang once the dovecot-auth sessions start to pile up.
