It would be a big helpuntil the problem gets fixed. I had to stop xinetd and dovcot then using =ps-aux I watched until the process went down to normal. I started back up =theservices and all is fine. I have my xinetd at 600 which covers the users =andthe other services I would think? Any other help would be appreciated on this. _____ From: Marcelo Caparroz [mailto:marcelo.caparroz (at mark) gmail.com] Sent: Thursday, October 19, 2006 3:59 AMTo: coba-e (at mark) bluequartz.orgSubject: [coba-e:07619] Re: HELP - excessive dovecot-authI 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 =processesor 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 itīs 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 =processand the dovecot go mad! I have made many test and observations, if someone want to talk about, =mailme, or skype me.

It seems like =Iam missing something in a config, but I do not know what or where. Like =Inoted the CPU does not go up. I end up with pages of dovecot-auth =processes that are stale or in a Sleeping state.
