930943 - memory leak on bitstamp order book page

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[David Balažic]

Opening the URL gives a steady increase in the RAM usage, until it reaches about 2GB when the process crashes (the Firefox crash dialog appears, I sent several such report in the last few days).

If the the tab is closed before the crash, the RAM is freed (judging by Task Manager).


about:memory

The Free Memory button do not seem to have any effect on this.

I can reproduce the problem with FF 24.0 on:
 - Windows XP Pro SP3 (32 bit)
 - Windows 7 Pro SP1 64 bit
 - Windows 8 Pro 64 bit

The problem happens with a freshly created profile and running FF in safe-mode.

A fellow reports that on debian there is no such problem.

Uploaded a memory report. In that moment Task manager showed about 1GB of used RAM ("normally" it is about 100-200 MB).

Opening the URL in Internet Explorer 10 on Windows 7 64-bit behaves similarly:
 - RAM usage increases until about 1,8 GB
 - CPU usage of page goes to 100%
 - "page not responding" printed in bottom bat, after clicking "Recover page" IR crashes

So it is the page doing something bad, but FF should not crash in any case.

Same in v25.0

I fail to repro against Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 ID:20140127194636 CSet: b8896fee530d and

and MSIE 11.

Still an Issue?
Maybe the site changed?

I guess the site changed, the problem does not happen any more.
(the page does not seem to auto-update the content any more)
