206862 - Mozilla mail leaves open connections to imap server

Status: RESOLVED DUPLICATE of bug 115349

(MailNews Core :: Networking: IMAP, defect)

Description

[Bart Prescott]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3.1) Gecko/20030425
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3.1) Gecko/20030425

Each time it starts, and as you browse different mail folders, Mail leaves port
connections open to the imap server (Cyrus), eventually, it becomes impossible
to browse mail folders on the server.

On the client machine each time a folder is browsed, a port connection is left
open (in TIME_WAIT state as viewed on TCPView) on the server the port connection
appears to be left open. Eventually the client PC needs to be rebooted to clear
the open connections and restore functionality.

Reproducible: Always

Steps to Reproduce:
1. Start TCPView (sysinternals.com)
2. Open Mozilla Mail
3. browse several imap folders
3. note imap connections
4. close MAil
5. note imap connections left in TIME_WAIT state

Actual Results:  
Several port connections left in TIME_WAIT state
If Mozilla browser is open at the same time after Mail is closed, the ports are
left open in the "ESTABLISHED" state.

Expected Results:  
Closed all port connections.

Yes, it looks like that I'm seeing the after effects of the process described in

Sorry, missed it in my search!
