Hi Berndt, I have seen the exact same symptoms and think I've finally found the cause of the problem. Once in a while netatalk creates an .AppleDouble file in my maildir. Courier tries to use this as mailfolder but as it does not have the proper structure the imapd process seems to hang forever and at the same time looses it's parent process. So for now deleting the .AppleDouble folder and killing all imapd processes with a parent process of 1 which was created by the user with the problem, seems to solve the problem. This is of course a workaround, and I think courier should fail a little more gracefully when it encounters bad directories.
