280046 - Does not release pagefile after multiple large downloads

Status: RESOLVED EXPIRED

(Toolkit :: Downloads API, defect)

Description

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

Whilst downloading multiple files from the above site, the pagefile use in
Windows Task Manager creeps up (more noticeable when downloading the larger
files) an and the processor load becomes very heavy. When the downloads are
finished, processor activity drops but the Page File usage is still high and is
not released until Firefox is closed. First noticed this when the machine ground
to a complete standstill after having downloaded 20 or so files. Page file usage
on my machine normally around 140Mb, now sitting at 271Mb after more downloads.

Reproducible: Always

Steps to Reproduce:
1. Open Firefox and also have Windows Task Manager open showing the performance tab.
2. Go to above URL (or indeed any repository of large files)
3. Double click on the file wanted and start to download to chosen directory on HDD
4. Repeat step 3, with the aim of downloading all the files in the remote
directory onto HDD. I almost continually had 4 files downloading simultaneously.

Actual Results:  
Very heavy processor usage and page file usage crept up until machine eventually
crashed. When repeated, same thing happens but I stopped when Page File Usage
got to 271Mb so that I could observe behaviour. Page file still not released
after 30 minutes.

Expected Results:  
Not hammered the Page File quite as much and should have released Page File when
downloads finished.

P4 2.8Ghz running on an Intel 845 based motherboard. 256Mb PC133 RAM.
Windows XP SP2
Internet connection is across a LAN. 2Meg ADSL via a Microsoft ISA proxy server.

Problem stops happening if you click Clean Up. List of downloaded software was
very long. Have started doing downloads again and the Page File problem is much
slower in happening. Surely the download manager shouldn't do this?

This is an automated message, with ID "auto-resolve01".

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.
