[Courier-imap] courier-imap (Debian testing) processes hang

[Fen L. <fe...@id...>]

Hello -

I just upgraded to 3.0.2-2 (testing) and now processes hang :(

What happens is a user can update a folder and view an email, and then
they're stuck - nothing else works.

In mozilla-thunderbird (0.5-4) I get "Server XXX has disconnected."

On Macintosh (Panther) Apple Mail, the error is: "Connection failed:
There may be a problem with the mail server or network"

On Windows Eudora 6, it says "IMAP connection to server XXX has been
broken"

The various /var/log files don't show much   But the processes keep
hanging.  After killing these processes, another folder may be
retrieved before it hands again.  You can see four sets of hung
processes (couriertls/imapd) in this listing:

I'm running courier-imap/courier-imap-ssl, openssl 0.9.7d-1 and
postfix 2.0.16 on Debian testing with kernel 2.6.3 on amd athlon

Hope this helps,
