Status: RESOLVED WORKSFORME

(Toolkit :: Downloads API, defect)

Description

[Graham]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

When downloading files to a mapped Network Share from here:
http://www-307.ibm.com/pc/support/site.wss/MIGR-4Q2QAK.html or here:
http://www.nvidia.com/object/winxp_2k_61.77 or anywhere else the local system
becomes almost 100% unusable with no available resources for any task.
Download the same files locally and there is no problem whatsoever. Download the
same files to the same mapped network share using Internet Explorer and there is
no problem (IE downloads locally and then copies the file to the network,
Firefox does not do this and that seems to be the issue?)

Reproducible: Always
Steps to Reproduce:
1. Download any file to a mapped network Share
2. System resources completely consumed
3. Cancel Download manager (this takes a long time to access)
4. System resources are instantly returned and OS/Apps become usable

Actual Results:  
Local system resources are completely consumed. OS and all running apps become
almost 100% inaccessable. Took several minutes just to be able to access
download manager and cancel the download. 

Expected Results:  
Not take over system resources

Running Windows XP SP2, Mcafee 8i, mapped share on a Windows 2003 server using
TCP/IP - DHCP.

Is your target directory on the network share accessed via a drive letter or by
UNC (i.e. \\server\path\)? 

Comment 2

[Graham]

Mapped drive (drive letter)  Z:\software\moz\

If I unmap all shares on the server and download to the target directory via UNC
the reported issues does not exist (UNC with the drives mapped and the problem
still exists).

Comment 4

The issue in Bug 296092 sounds exactly the same as I've experienced with the 
exception that I'm saving files from a Windows 2000 client to a Windows file 
share on a very very under utilized Windows 2003 server running dual gigabit 
ethernet cards, dual processors, 2gigs of ram with about 80gigabytes of free 
disk space. Issue occurs even if I'm the sole user attached to the box.

I've noticed the same behavior detailed in 296092 where IE saves files to the 
local machine then when download finishes tranfers the file in file to the 
network resource, Firefox appears to write the file to the network in real time.

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
