148337 - opening some webpages sometimes hangs Mozilla.

Status: VERIFIED DUPLICATE of bug 58339

(Core Graveyard :: Plug-ins, defect)

Description

[Jonas Perleryd]

Sorry if this one should not be on Rhino but I get the impression that the crash
occurs when executes the javascript.

Problem description:
When opening some web-sites, e.g www.aftonbladet.se and sometimes www.dn.se
mozilla freezes. It usually happends the loading of the page is about 90 % done.
And I have left it for 30 mins but the situation seems unrecoverable.

This happens every once and a while (daily), but I have the experience that when
it has happened once it happens quite frequently until rebooting the PC (can't
see how this can have anything to do with it since I kill all mozilla and java
pid's ??). 

Anyway, other days I can visit the page 20 times without problems and Mozilla
runs stable for 10 hours. Worth noting is that this is news-sites and the
contents changes several times per day. 


I am happy to take a debug build if you have problems re-producing it, just give
me instructions.


PS. 
Would it not be possble to change the startup so that the Mailer and Browser
does not have the same parent pid. It is very annoying that the Mailer crashes
together with the browser when the browser goes down several times every day and
the Mailer is quite stable, the last crash I had was on 0.98 (bug# 124684)

Rhino is a standalone language engine. This bug belongs in the 
browser component, so let me reassign to Browser-General until
we can find out more.

Jonas: if you can launch Mozilla from a console window, try this:

      [(path to Mozilla)] ./mozilla -profilemanager

This will bring up a prompt allowing you to create a new profile.
I'm wondering if the problem goes away when you run Mozilla 
under this new profile -

Did create a new profile with absolute minimum settings (only changed the proxy)
and it hanged instantly (as did it with my old profile when checking before I
created the profile).

Btw, It was probably obvious but when it 'hangs' I cannot close down mozilla
normally but have to kill it.

Jonas: thanks. More questions:

1. What build ID of Mozilla are you using? Is it up-to-date?
2. Are you using a proxy server; for example, WebWasher?
3. How fast is your connection to the Internet?
4. What version of Linux are you using?
5. What window manager are you using on Linux?
6. You are able to load the site most of the time,
   and Mozilla only hangs occasionally, right?
7. I notice that http://www.dn.se uses the Flash plugin.
   Could this be a duplicate of bug 58339? (are you playing
   any audio in the background?)


Myself, I have not been able to hang at http://www.aftonbladet.se
or at http://www.dn.se. I am using Mozilla trunk binaries from 
2002-05-30 on WinNT and Linux over a T1 connection.

I do see we've had a number of bugs reported on 
http://www.aftonbladet.se, however, including:

bug 112165  Mozilla hangs, sucking 100% CPU
bug 140316  Incorrect page rendering, text doesn't flow around images
bug 132672  Old FocusEvent listener is not removed from document 


cc'ing people from those bugs to see if they are hanging on this site,
and if they know why the hang only happens occasionally -

Maybe not related, but I see a freeze as Java (or maybe other plugins) is
started. This sometimes takes 5-10 seconds.

Question: are plugins loaded started on the main event thread (thus freezing the
UI and page rendering), rather than in a separate thread?

Comment 5

[Phil Schwartau]

That depends on the OS, I believe (I'm thinking of Mac OS9, for example).
cc'ing Beth for this Plug-ins question -

Hi Phil,

This is definietly a dup. to 58339 which problably explain the sporadic part, I
did not take the mp3 player into consideration when looking for pattern.

Anyway, when the hanging occurs I let it stay like that for 5 mins, then turned
off the playback of the mp3's and within 45 seconds Mozilla 'comes' back.
Re-produced 5 times now so I take it for a fact.

I guess the rest of your questions are superfluous now but just in case:

1. Build ID 3003052918 (but have seen the same on about all builds since I
started to use Mozilla all though it has gone worse over time (probably because
I am using the audio device more often now;-),  v. 5 r47 of the flash plugin.

2. Yes, do not know which one but it is a http-proxy

3. several Mbits

4. MDK 8.2

5. KDE3.0.1

Thanx

Jonas: thanks! 

I will move this to the Plug-ins component for parity, before 
marking this bug as a duplicate per your findings. 

I have cc'ed you on bug 58339 so that you can follow its progress -
