Title: 100% CPU load on www.os2world.com ?
Post by: rudi on 2009.09.14, 09:13:56
Hi folks,

not sure if it's only me, but since about 2 days I experience a 100% CPU load
situation when visiting OS/2 World pages with a FF of the 2.x series. Usually
this lasts for about 15 - 20 seconds after each page change, which makes it
pretty hard to look around here...

Hi guys,

I have both a good news and a bad news.
The good news is: I can't confirm this either on FFx 2, SM (on ecS) nor on IE7 / FFx3 (on XP).
I have no clue what may cause this... are you logged-in or logged-out? Does that matter?

Now for the bad news.
I wanted to see if there is perhaps something woring with the pages served... and I lloked for te pagesource.
HOLY SHIT!!
Each and every page served by os2world.com is compromised!! Please take a look at the page source (View -> Page Source) and go straight to the bottom: Can you see that immense <form> element?
Since I doubt that os2world.com is selling Cialis etc. - can someone here have a look, please?

Once that is solved, let us see what other problems are solved as well. ;)
Cheers,
Thomas

Same problem here, the official FF 3.5.3 and FF 3.5.2-media from netlabs gives me 100% on cpu.

Hi all,

seems that the fishy <form> tag (which is REALLY huge) gives problems to the eCS-flavor ob Mozilla browsers?
(Have no problems on the "evil" platform...)

Cheers,
Thomas

Evil platform OK here (IE6), Epiphany (Debian) also OK. Perhaps, it's a problem of FF - comming clear, I have not tried FF because I prefer responsive apps from the big ones even if they are less mighty.

I had the same problems. However, they seem to be gone now. The source code doesn't show anything suspicious. Did you change something?

Hi,

I can approve that what I saw is now gone from the source view.
(BTW, I have a screenshot of that ...just in case nobody believes me :-P )

Regarding "did you change something":
I hope so. ;) I mailed Kim about that issue around noon and he immediately forwarded it to Tommy. Seems like he's already fixed it (at least for that strange <form> thing to be removed). By the way - I pasted the entire <form> tag into a text file to see how large it is. ~580K. Whoops. I must admit that I understand how that could impact on a web browser engine (even if it was non-display'ed). However it would mean that eCS-based browsers have a problem with this... (since on other platforms it appears to be not an issue).

Also, I still don't understand why I did not have these problems with my SeaMonkey 1.1.6 (IIRC) on eCS back home. I went to os2world.com on Friday, Saturday and Sunday without issues... strange...

Anyway:
Did I get you correctly, that the CPU usage is back to normal now? Can others also confirm this?

Regards,
Thomas

On sunday my SM1.1.x crashes whenever 4 or 5 tabs are open. The browser was inresponsive and all 2 cores are at 100%. Total system memory usage goes beyond 1.1GB and then SM silently closes itself.

FF, whichever comes with eCS2.0rc2, was able to start loading about 7-8 tabs. Total memory usage was about 1.45GB as FF crashes too.

when you say "4 or 5 tabs" or "7-8 tabs" in these browsers, does that mean tabs with contents from os2world.com, or "in general"? And... is there a change with the current pages from os2world.com (ie less/no crashes) ?

Thanks,
Thomas

About the "evil" platform , as I said earlier I also tried os2world.com with Windows (XP). Firefox showed the same behaviour and Explorer, in fact turned itself off (crashed). So this was not an only OS/2 problem.

oops, me stupid. I should have read more carefully... you are right, you mentioned earlier that this also affects the evil platform and FFx. But ??? why didn't I experience that, heck... this could have saved us time. Phew, anyway... glad it was solved.

Thomas,

I am curious to see the screenshot - and not because I dont believe you, but because I am interested in what it is and was intended to do.

Can you post it in the Staff Area so the staff can review it?

Best,
Rob

Yes, I meat 4-8 tabs with threads in this forum. Luckily the problems seems to be solved now (7  tabs open, only 900MB RAM used, and the browser is responsive as usual).
