Hi,
I routinely use thunderbird to access mail on a cyrus IMAP server with
very large folders (thousands of archived messages).
IMAP support in the 3.1 series seems quite stable to me (whereas 2.x had
frequent problems with folder indexes and 3.0.x tended to hang randomly
while performing server operations)
The only problem I can think of is that if you have used the default
settings for the message search feature, thunderbird will attempt to
build a full-text search index by downloading every message on the
server (body included) when it is first run. Thunderbird will try
downloading messages from multiple folders in parallel, which might
cause a hign load on the server resulting in substantial delays when
listing folder contents.
If thunderbird is indexing messages (look at the progress indicator on
the status bar), try leaving it alone until it is done -- it's a
one-time process.
If, on the other hand, everything is idle, I'm sorry but I have no idea.
HTH,

The problem turned out not to be with Thunderbird at all, but with the
courier-imap configuration. I found in /var/log/messages some instances
of this:
imapd-ssl: Maximum connection limit reached for ::ffff:10.0.0.1
It appears that the default configuration for MAXPERIP (maximum number
of connections to accept from the same IP address) was set to 4. (I
assume it's the default, since I never changed it myself.) Changing the
value to 10 eliminated the Thunderbird problem entirely. I don't know if
some other value between 4 and 10 would work as well. I'm happy with it
as it is now.
I'd recommend 10 connections per concurrent account that connects to
the server from the same IP. If you're running multiple accounts, like
kashani-list@ and kashani@ in my case, you'll want at least 20. Same
thing applies if you're running webmail for multiple account because all
account access will originate from localhost.
