When I'm moving mails, dovecot takes up to 10% of the CPU-time.

Hi Borthers/Sisters
Thanks for all the developer(s) and for all the hard work spent on build this great piece of software! I loved Dovecot since it is really easy to set up and really fast but I am really new to it (only 2 weeks and half). Right now, our server configuration is:
Server: Apple Xserve G5 dual RAM: 4GB Number of Users: ~ 150 IMAP only users Authentication: LDAP Mailboxes sizes: ~200GB Dovecot version: 1.0 Beta 5 (I am looking forward to beta 7 that was released today) Email client software: mostly Thunderbird 1.5
Right now, we are experiencing occasional problem with imap users unable to connect to the server. With beta 3, we had to restart the dovecot/imap processes almost every 3 hours. with Dovecot beta5 we still have to restart the processes but it seems to occur every 3 days (Friday and Yesterday) and only in a peak time (around 3pm). I am waiting to occur it again and I will be able to grab more information about the number of processes, users, virtual memory, etc, etc. So, at this point, I don't have much information to debug the problem. Let's wait.
I guess we have here a nice machine (xserve) and not a huge number of users (~150). So, I would expect that our server would handle the load. But having to restart Dovecot once a while, as I described, is not an option (users are getting frustrated). :( Maybe with Beta 7 with the feature "Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is" can stop our nightmares :)
By the way, our dovecot.conf is basically the default sent with the software. We haven't changed much there!
Meanwhile, I'd like to know, if possible, whar are you using to run Dovecot like hardware, OS version, number of users and problems that you are experiencing. I'd like to compare with my setup and if it is the case, migrate to pure Linux or FreeBSD if it is more stable than OS/X!
