Normal debugging output doesn't show a good reason for the activity, so worth looking at.

Can't reproduce with trunk (the freeze, I mean). Please try with 0.8.4, and if that's still buggy, with trunk. Some plugin freeze bugs were fixed since 0.8.3.

Yes, it freezed only second time. First time it displayed background and nothing was changing while 100% CPU. After killing it, trying youtube then again that page it freezed but did not use 100% CPU this time.

This is SWF9 and uses SWF9 tags, so it will not work (not supported yet by Gnash).

The high cpu usage comes because it executes tags in a sprite. It will probably be fixed as SWF9 support is implemented.

It doesn't freeze for me. Did I understand correctly that it only froze the second time for you?

Hi,

I have Debian (sid)

ii  gnash                                 0.8.3-6
ii  gnash-common                          0.8.3-6
ii  mozilla-plugin-gnash                  0.8.3-6
ii  iceweasel                             3.0.1-1
ii  iceweasel-gnome-support               3.0.1-1

When I entered first time page http://www.yearbookyourself.com/
background appeared but progress bar was not proceeding and CPU usage went to 100%.
I killed iceweasel and tried youtube its working.
I tried the same page second time. This time background of the page was black, browser freezed and was not responding, while CPU usage was not abnormal.

The only errors that I was able to track down in console were

Error: [Exception... "Component is not available"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: file:///usr/lib/iceweasel/components/nsSessionStore.js :: sss_saveState :: line 1896"  data: no]
Source File: file:///usr/lib/iceweasel/components/nsSessionStore.js
Line: 1896

But I dont know if this has something to do with this case.
