Dovecot beta 5 + dovecot lda, solaris 9 sparc.
Dovecot seems to use a lot of memory with large Maildir folders, ( 300-500 mb folder - 100-200 mb process), something I never noticed with similarly large mboxes. Is that expected behavior or are my observations incorrect.

It's not expected behavior. How many messages do the maildirs have?

The biggest folder I can find now has ~70000+ messages and when that's open the process grows to 116mb, I'm not seeing 200mb+ process sizes today, but I certainly have seen them, so I'll keep looking for patterns.

Well, it's not necessarily a bug then with that many messages, although it still does sound a bit high.
It would be useful if you knew how to reproduce this with some specific mailbox. Then you could check:
- How large are dovecot.index* files for the mailbox (especially dovecot.index.cache)?
- How large is the dovecot-uidlist file for the mailbox?
- When closing the mailbox, how much memory does the process take now?
- Does it use all that memory immediately when opening the mailbox or only after doing something?
Especially useful would be if you were able to do this manually, eg.:
su user # to get correct uid/gid MAIL=/home/user/Maildir /usr/local/libexec/dovecot/imap x select mailbox x unselect
