I've been having this same problem with brand new Mac Mini's and Safari. I just tried a complete re-install of OSX and it still did it after a couple minutes of web browsing. And this machine has absolutely nothing extra loaded on it. I am using the Apple bluetooth keyboard & mouse so a couple of your posts are making me wonder if this is the problem. I'll try using a wired keyboard and mouse and report back what I find.

I havehad the same freezing issue with all web based programs. It did not occur until the most recent update of OSX.
I have dont a complete wipe and started from scratch, however the matter still occurs.
Im using Google Chrome and still get the issues.
I believe that it may have something to do with internet sharing and I wonder if anyone else who has this issue is currently using internet sharing (from Wi-Fi) to ethernet (Xbox or other).
I have currently disabled internet sharing and will see if this resolves the matter.
Late 2010 iMac 27inch, 16GB Ram, 2Tb harddrive, i7 (You would think that would be enough for it not to crash).

Froze again, so not internet sharing.
It is definitely internet related.. So I am going to stop having multiple tabs open and just create new windows when I need them. Hopefully this will resolve it. If not... necks will be snapped.

The past couple of weeks I've had a similar issue, and tried a number of solutions.
I realised that this started after I set the System Preferences/Desktop to change every 5 seconds, instead of the previous every 1 minute, using iPhoto photos as the source: with 12,000+ photos in the file.
I have changed Desktop back to change every 1 minute and the locking up issue has gone. I can only surmise that the Desktop, running away in the background, was just demanding too much of the MB Air and it threw in the towel!
Maybe something to look at for those who are still struggling?

BK117, that is a very good idea. I had a freezing issue and posted in a much earlier post that it had to do with the Sophos Anti Virus program. After reading your post it seems like there is something in common here. Everyone should look at the programs they have that run automaticly in the background as it seems Lion is having issues with those. As soon as I deleted Sophos my problem went away, thanks to someone who had posted that a while ago on this same thread. My MB is a 2009 Dual Core with 4MB of RAM and I upgraded to Lion and iCloud at the same time just to be clear it is not a new machine. I've had no freezing since removing this program and prior to that it almost made my MB unusable and it continually frooze.

I'm having the same problems, but I can definitely say that my issues have to do with flash content in Safari. It's not even every page, but certain sites, like TechDirt, AppleInsider and others, Safari/my iMac will lock up something awful. I barely have enough memory to get activity monitor opened up and notice that 'Safari Web Content' is taking up like 2GB worth of Real Memory. If I quit that process and close out the problem page, all is well again.
Apple fix this!! It's been happening for a couple weeks now!

I am having the same problem! It seems to be when in Safari. But what's weird, I can be listening to Radium, watching a video with VLC or streaming anything else, and they will continue to play, but the rest of the PC is frozon. I can't stop or pause the streaming, and can't do anything else. This is really frustrating and I know Apple sees this! I hate them when they just ignore obvious problems, instead of saying, hey we recongnize the issue and we are working on it. See how easy that was! Now fix this!

Another "me too". Safari locks up my entire machine for 40-45 seconds when going to certain sites like ebay, igoogle, and this one (apple support communities). My activity monitor sticks on kernal_task almost every time, sometimes SystemUIServer. It's weird how it locks up for the same amount of time everytime. If I go to another open app to do something while I wait (including finder) it too is a locked up spinning beach ball.
I seem to have the same problem in Firefox although I haven't thoroughly tested that theory. Another weird thing is that this is only happening on one of my macs...I have an iMac 27" i7 that is affected, a 15"mbp i7 that is fine (I just played a youtube vid) both with all current software and pretty much setup identically. Another mbp with lion 10.7.3 but still on Safari 5.1.4 that works fine. And another iMac running Snow Lep with Safari 5.1.5 that works fine.
Good luck finding this conflict, Apple. We're counting on you.

Make sure you do the Software Update, and get the lastest firmware update on your Mac and update on AirPort Utility.
I believe it has to do with the specific Mac model that has trouble detecting wi-fi auto-join.
I did the firmware update on my MacBook Pro, and it resolved the Safari hang problem. (All my other Macs did not have this problem, except for MacBook Pro, and the Firmware Update fixed the problem.)
If it is another model of Mac that you have trouble with, then send Apple a bug report on the specific model of machine you are having trouble with.
I believe the hang problem has to do with the user-interface (pop-up auto-join window) in an attempt to access the internet, and failed to bring up the user-interface window, and get into a deadlock because it is waiting forever for the user-interface (UI) from SystemUIServer to respond, but since the UI never got waken up, it never responds to the request, and causes an infinite wait.

Nicoladie, that is the exact opposite of my experience. The mac that has the problem has the most current software/OS, current firmware, current airport utility, has wifi turned off and is connected to the internet via ethernet.
I've restarted the router, modem, computer many times. Disabled all plugins (3). Tried plugging the computers ethernet directly into the modem bypassing the router, and sent plenty of bug reports (everytime I had to do a force quit). Also, I've run Diskwarrior, repaired permissions and any other mumbojumbo I could think of doing.
I think it Java.

Did you turn off all Safari Extensions? Badly written extension is notorious in crashing Safari. Also, when Safari update to a new version, the old Extensions tend to fail to work.
