Default Zimbra IMAP hangs when connecting Thunderbird to a full mailbox for the first time

Hello,

I am hoping this thread is relevant.

Running Open Edition zcs-5.0.6_GA_2313.DEBIAN4.0.20080522112011.tgz
About 10 users using Thunderbird Clients (set to use a max of 5 connections)
Zimbra IMAP is set to 200 connections at the moment

I originally installed without the IMAP proxy.
After reading this thread I installed and activated the IMAP proxy.

Shortly after this we reinstalled a desktop PC for a user.
The first time Thunderbird connected to the user mail box to fetch and sync the mail, the Zimbra IMAP process stopped accepting connections on 143 or 993 from any of the hosts on the network, although I could telnet localhost 143 from the debian console and get a connection.
After some time we restarted Zimbra and the problem went away.
We have experienced no further problems since then, but we are nervous that we will hit the same problem again.

Please advise.
