From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.0rc2) Gecko/20020510 BuildID: 2002051006 A Flash ad for Ananova Online Ticket Sales at http://www.ananova.com/news/ can cause the CPU usage to jump to 100%. This effectively hangs Mozilla, and lasts for several seconds. Other apps are usually still usable in this time. Other flash ads on Ananova seems to be OK. It may be only part of the ad sequence that causes the hang, as the browser is usable for much of the time. The ad itself occasionally freezes for a while. Task Manager's CPU usage graph shows a regular pattern of plateaux of 100% usage falling to about 50% in between. Reproducible: Always Steps to Reproduce: 1. Go to http://www.ananova.com/news/ 2. If online ticket sales ad is present, CPU should hit 100% automatically whilst looping, or e.g. if right-clicking on ad a few times. Actual Results: Page and ad displayed correctly. Right-clicked on ad at bottom of page (one at top has the same effect) - first time no problem, second time CPU went to 100% for >10 seconds and Mozilla stopped responding during this time. Although the system recovered, the hangs continued on a regular basis even when the browser window was underneath several other windows. Expected Results: Displayed the page and ad without eating my CPU :) OS : NT 4 SP6 IE 5.5 displays the ad correctly without the CPU issue.
going to http://www.ananova.com/assets/ticketsbanner.swf seems to send mozilla into 100% cpu usage seen on 20020511 on win2k
we have a lot of bugs for this issue...cpu going 100% ..hm. gotta look
Also seen on Win98SE running build 20020417. IE 5.5 does show a similar oscillating CPU usage as the animation loops, but never goes above about 70%; Mozilla still hits 100% and doesn't like it. Viewing just http://www.ananova.com/assets/ticketsbanner.swf shows the oscillation but it does not reach 100% on this system. Perhaps the difference is that http://www.ananova.com/news/ shows two copies of the ad?
