279897 - Thunderbird loses connectivity and hang all the rest of the internet applications

Status: RESOLVED DUPLICATE of bug 173924

(Thunderbird :: General, defect)

Description

[uri]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Thunderbird version 1.0 (20041206), running on a Windows XP SP2 (but also seen
on Windows 2k SP4, RedHat ES 3 and Fedora Core 3). 
Thunderbird will sporadically lose connectivity with the mail server. it just
won't do anything, it writes "checking email..." or "sending email..." and it
will remain like this until the application is closed by pressing the close
button (the little x on the top right). this will cause thunderbird main window
to disappear but thunderbird will still be running, taking with it all the
connectivity from browsers, ftp clients, etc. the only way to solve this is by
killing thunderbird using the task manager, disable the ethernet card and
renewing the ip.

Reproducible: Sometimes

Steps to Reproduce:
1. open thunderbird. get new email.
2. write a new email, press send. nothing happens, also the browser stops working
3. all the connectivity is dead

Actual Results:  
n.a

Expected Results:

Isn't this a dup of 278283? I'm not "sufficiently empowered" to change its
status though. I get this about every day.
