There's nothing to debug in dovecot here. Your server is overloaded by about 55 times. Buy 55 times as many servers or do something about your webmail interface (maybe a separate webmail cluster).
As you can see the numbers (55.04, 29.13, 14.55) the load was busy getting higher when I took this snapshot and this was not a normal situation. Usually this machine's load is only between 1 and 4, which is quite ok for a quad core. It only happens when dovecot start generating errors, and pop3, imap and http get stuck. It went up to 200, and I was still able to stop web and mail daemons, then restart them, and everything was back to normal.
What is your webmail server (and version)? Maybe it is buggy?
