220952 - Virtual memory continues to increase with use; page faults intolerable when restoring window.

Status: RESOLVED EXPIRED

(SeaMonkey :: General, defect)

Description

[Mark Lindemann]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5b) Gecko/20030827
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5b) Gecko/20030827

As I continue to use Mozilla, the Virtual Memory usage continues to increase. 
Sometimes, it does go down a bit but, overall, it increases.

If I "minimize" the page and do other things, when I "restore", it takes an
intolerable amount of time because of hundreds of page faults.

I have been running an instance of Mozilla for several days.  According to
TaskInfo2002, the total Virtual Memory in use currently (as I write this) is
368,840 KB; the Fault Count is 315,398.

Firebird seems to behave the same.

Thank you.

I wish to report the following data:

I'm running Windows XP SP2 with NO virtual memory, in a system with 1GB of RAM.
I'm using Mozilla 1.8b, and I'm measuring the memory usage through the "private
bytes" column of Process Explorer (www.sysinternals.com).

After having used Mozilla on and off for a few days for browsing and reading
mail, without closing it, I closed all tabs of the browser window except one, in
which I entered the URL "about:blank". I also closed the mail window and cleared
the cache in the preferences. The only Mozilla window that was left was the one
showing "about:blank". After this, Process Manager indicated a use of 174472
kbytes by Mozilla. Minimizing Mozilla made only a very slight change in this
figure. I then closed Mozilla and started it again, and again opened
"about:blank" in a single tab of a browser window. The memory usage indication
given by Process Explorer was then 17588 kbytes.

I think this is a clear indication of some memory management problem in Mozilla.
For some special reasons, I don't use virtual memory in my system. This behavior
of Mozilla means that I have to close it and restart it every few days, to
prevent it from eating up too much RAM.

Attachment: Screenshot of TaskInfo2003

According to TaskInfo2003 (see attached), my Firefox is currently using:
     InMem KB:	85,228
   Private KB: 126,436
     Total KB: 474,124

Seems like a lot to me, and it doesn't seem to ever go down by much.

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
