To reproduce the issue:
1) click on "Clear Display" in Console.app
2) go to http://www.adobe.com/software/flash/about/ and the error will show up in the console.

The error must be Flash related. Sometimes, the whole System is unresponsive, freezing everything but the mouse. There is no official response from Adobe or from Apple, so we can only hope and wait. Please check your Console.app for this error and respond to any of the existing discussions.

[Update] the error message also seems to have surfaced in 10.6.4 already, as visible in the Apple Discussion Forums

[Update] installing the Adobe Flash Player 11.0 from Adobe Labs seems to at least minimize the freezes, but still the console messages appear.

[Update] i posted a poll on insanelymac to see which browsers and systems are affected. please also post your results there!

[Update] the new Beta 2 11.0.d1.98 of the flash player is out (thanks JP Hansen)

[Update] The Flash Player 11 is officially released. It seems though, that not all issues are resolved with Mac OSX Lion compatibility.

[Update 23.12.2011] more than 6 months after the issue was reported, (and we have Apple Mac OS X 10.7.2 and 10.7.3 in beta) there is still no update on this issue from Adobe. Please write your concerns to the Adobe Forums in the existing thread to have them fix the issues! Especially for SSD owners this is unacceptable!

[Update] I posted to the Adobe Bugbase with a bug description. Hope they will respond now.

via tc electronics: "For just two more days, today and tomorrow (June 15), you can save 50% on all TC Electronic plug-ins for PowerCore and Pro Tools - plus a few additional ones! For example, you can get the amazing M30 reverb plug-in that runs natively on your computer for only $35!"

This offer might be especially interestin for people owning the tc powercore units. As I own the tc powercore compact (only available via ebay these days) i was wondering if the Access Virus PowerCore Plugin sounds as good as the original Virus synthesizer. The PowerCore PCI is currently priced 399€ at thomann, the TC electronic PowerCore Firewire 19" variant is 998€ (also thomann). UPDATE: you can get my powercore compact from the audio sellout list.

"The M30 Studio Reverb is a simple to use, great sounding reverb that is powered by AlgoFlex™ - a new high definition TC technology that enables hardware quality and predictability to be ported to native software.
TC Electronic has been at the forefront of effects development for decades, and our reverb algorithms can be found in the best recording and mixing environments in the world. With its great sound M30 is a unique addition to VST- or AU compatible applications running with Mac or PC.[...]

They claim you can unsubscribe from their newsletter, so quite a bargain. I just downloaded the plugin; as i really like the quality of the TC plugins, I can recommend this one. (see also a Video Review on Youtube for the tc m30)
