139447 - bad memoryleak (1Mbyte/s) visiting bugzilla pages

Status: RESOLVED DUPLICATE of bug 120712

(SeaMonkey :: General, defect)

Description

[harm]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.0rc1) Gecko/20020417
BuildID:    2002041711  (v1.0 RC.1)

Following the URL (bugzilla query) mozilla starts to eat memory as soon as the
query is finished. It consumes memory at a rate of +/- 1Mbyte/second.
Interesting to see is that if you hit back the memory leaking stops.



Reproducible: Always
Steps to Reproduce:
1. click url
2. open taskmanager
3. wait till url (bugzilla query completed)

Actual Results:  mozilla memory consumption increases with a rate of about 1
Mbyte/second as soon as query is completed. 
Starting at about 17Mbyte memory use, I killed it when it got to 130Mbyte memory
use (see atachment)

Reproduced the problem. Only, this time it took up 306 mb!. Attached are: a
snapshot of task manager and the html source of the bugzilla output for the url.
the time right now is 23/04/02 8:00 am pst. Mozilla rc1 on win2k sp2.

Attachment: the html text of the bugzila output

I am attaching the text of the bugzilla output screen. This is not the html
source. I tried to open the window. It pegged cpu to 100% for a long time.
Anyway, the idea is to demonstrate that the it does not require 306 mb of vm.

I have closed the bugzilla output window. But the memory has not been returned,
it fell from 306 mbn to 281 mb.

[Boris Zbarsky [:bzbarsky]]

how many bugs does that query return?

I suspect this is a dup of the "showing a large bugzilla query takes lots of
ram" bug.

What bug# are you refering to ?

Comment 8

[harm]

the query returns about 3000 bugs, taking up about 270 kilobyte in text.
Note: after that when browsing to other pages, the memory (hundreds of
megabytes) is _not_ reclaimed.
