92685 - persistant http connections

Status: VERIFIED DUPLICATE of bug 92224

(Core :: Networking: HTTP, defect)

Description

[Jeroen Ruigrok van der Werven]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:0.9.2) Gecko/20010703
BuildID:    0000000000

I apologise in advance for the sheer lack of real data or steps to retrace the
problem, but I should bring this under the attention of people.

After visiting sites and getting flooded with pop-up windows on some sites (like
what happens sometimes when logging into planetarion.com) and leaving the
browser open on a site (like www.freebsd.org) only, after killing the pop-ups,
it seems that some http connection remains with the host of the pop-up window. 
In my case tcpdump showed that brandy.fortunecity.com was sending me a
continuous stream of data, about 3-4 k/s all from the http port.

Closing mozilla solved this problem.

Sample tcpdump:

It looks as if the supporting network code in mozilla hangs in a weird state. 
The funny thing is that netstat didn't show any persistant connections to/from
that host.

[gotta love wmnet monitoring your NIC interface in a dockapp]

Reproducible: Couldn't Reproduce
Steps to Reproduce:
1. No idea yet, as soon as I can I will report it.
2. It has happened to me before though, but I couldn't trace it back then to
what was causing it.
3.

Expected Results:  I think the connection wasn't cleared from the internal
connection state.  But that's just guessing, I really have no idea how the
sources of Mozilla are build up and I don't have a desire to delve into it,
since I have enough Open Source to hack as it stands. :)

FreeBSD 4.3-STABLE, no special hacks or whatever.

Compiled mozilla 0.9.2 from the ports/www/mozilla directory.

The server is not sending any data at all.

It looks like mozilla is retrying the connection on different ports. 
Could this be related to bug 92224?

Yes,

I tested the URL in that Bug Report and I got the same sort of problems as I
described.

I think this could be marked as duplicate of that Bug Report.  [Which I just did]
Thanks for spotting the other Bug Report, I did some searches but wasn't able to
find another one.
