379493 - Connection left in CLOSE_WAIT when opening link in external application

Status: VERIFIED DUPLICATE of bug 147659

(SeaMonkey :: General, defect)

Description

[Dean Serenevy]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.2pre) Gecko/20070111 SeaMonkey/1.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.2pre) Gecko/20070111 SeaMonkey/1.1

Opening a file in an external application (for instance, viewing a pdf in an external xpdf instance) leaves the connection that downloaded the file open until the external viewer is closed.

Reproducible: Always

Steps to Reproduce:
0. [optional] close all instances of xpdf
1. Visit a webpage with a link to a file that will be opened in an external application (for instance: http://refcards.com/refcard/catalyst-forda)
2. click the link and choose to open the file in an external application
3. netstat -p | grep CLOSE_WAIT
Actual Results:  
xpdf has an open connection in the CLOSE_WAIT state

Expected Results:  
the connection should be properly closed before exec'ing xpdf. (at least that is what I figure is needed)

sounds somewhat like bug 147659 (check lsof -i tcp | grep xpdf).  At the very least, fixing that bug should fix this.

Perhaps the same bug, though I do not have problems with open real files (as some of the comments in bug 147659 indicate).

[dean@teckla ~]$ netstat -p | grep CLOSE_WAIT

Er, nevermind, forgot that I filtered by tcp. I would call this a dup of bug 147659.
