"airport" process uses all of the memory an cpu

After I reinstalled my MacBook and updated to the latest version of Tiger (10.4.8) my airport network behaves very strange. When I boot my MacBook or disconnect/connect my Airport network a process called "airport" is consuming all the CPU and memory. It uses one core exclusivly and gows to 1,2 GByte of RAM (even more virtual Memory). This slows down the macbook to almost still and heats up the CPU.
The only thing I can do is to kill the process. Then everything works fine. But this is annoying.
It seems to make no difference if I use a wireless LAN or not. When airport is enabled then this bug occurs.

Checkpoint Secure Client installed, WLAN was working before latest update to 10.4.8

All I can say is that 10.4.8 seemed to worsen the IntelMacAirport problems, though I haven't seen this one yet... might try cleaning .caches, or trashing...
/Users/nnnn/Library/Preferences/com.apple.internetconnect.plist
/Library/Preferences/SystemConfiguration/preferences.plist
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
A couple of people said going back to 10.4.7 helped.

Thanks for the advise. But removing the plist and preferences doesn't help for my problem.

My coworker is having this exact same issue on his MBP. Other things to note is that it seems to happen when waking up from sleep when the ethernet is connected. Hopefully someone will have some answers for this...

I am the "coworker" referenced above. I have verified that this issue occurs whether an Ethernet connection is in place or not.
I have tried the following with no success in fixing this issue:
Reinstalled 10.4.8 Combo update (3 times)
Permissions
Disk Warrior/ fsck for disk problems
NVRAM reset
All caches cleared
chron jobs run
and looked for any 3rd party utils that might have been causing it.
It looks like a serious memory leak to me but what is causing this is still an unknown

My co-workers and I replaced our aging ThinkPads with MacBook Pros and we are seeing this problem. We upgraded after the out of box experience directly to 10.4.8, so can't say if this problem existing on whatever shipped with the MacBook Pros.
It seems to happen everytime OS X comes out of sleep with the Airport interface previously enabled, regardless if the last network you were on is available or not.
The only solution I have seen is to delete the com.apple.airport.preferences.plist file from /Library/Preferences/SystemConfiguration. This holds the list of Preferred Networks that are tracked whenever you join a WiFi network, so dropping the pref file will lose any WiFi network settings, and its entirely temporary since as soon as you join another WiFi network things are going to go crazy again. I see the same problems, massive RAM used and 90+% CPU on one of the cores.
This might be the worst bug an OS X update I have seen in 3 years of using the OS and I am terribly dissappointed this appears to be only and Intel Mac problem, my PowerPC based Macs still "Just Work".

My permanent workaround to this issue is to tell Airport not to remember preferred networks. To do this, you go to the Network System Preference, select Airport in the Show list, then click the Options button, and uncheck Remember preferred networks.
This isn't a solution for everyone though. If you have password protected networks, you would have to enter the key every time you connect. Since the only WiFi network I connect to is open, this is a decent workaround until this bug gets fixed.

I'm having the same problem with the runaway airport process. Interestingly when I go to "Options" in the Network prefs under Airport, I'm unable to uncheck the "Remember preferred networks" box. It's greyed out. Something is clearly wrong here.

I am seeing that too on a co-workers MBP.
I can reproduce this on my MBP if you click Options on the Airport interface if you are using a custom location. For some reason, you can't change the option to remember preferred networks with a custom location, only if you use the Automatic location.

We recently bought a couple of Intel-based iMacs, MacBook Pro and MacBooks and moved away from Windows. We all wondered why the **** is Apple promoting Bootcamp. Now we see the master plan behind this.
There are two basic solutions: Either Apple solves this problem very soon and makes life as it was before or many people like us will move back to Windows. We can not effort the time to play around with hardware and with mediocre software implementations. The Apple hardware is right and Apple will deliver the reason and the tools to switch back to Windows - the WLAN works very well under Windows. Bye bye
By the way: There are other helpful tools too: If you have all your data on the Mac partition, don't worry, there is a nice software called MacDrive. So you can access (read/write) all your data from within Windows.

On this thread, http://discussions.apple.com/thread.jspa?messageID=3492852, people that have Check Point Software's SecureClient are reporting the airport process using ~95% of CPU time.
I had SecureClient installed and I can confirm that if you uninstall SecureClient, the airport process works normally again. I don't know if this is the only source of this problem, but if you happen to have SecureClient, then you might want to uninstall and confirm if this solves your problem.
Also I would be curious if anyone is having this problem that has never had SecureClient, or any 3rd party VPN software.

I can confirm that at least some of my problem with the "airport" process was related to VPN software. After uninstalling the Cisco VPN client, problems dramatically reduced. Interestingly, I still have the Checkpoint client installed, but only rarely see problems with "airport".

I also have the Checkpoint VPN client installed. Since I disabled the favoured WLANs it worked for me. Of course it's annoying to connect to my home WLAN manually every time. But I don't have to kill the airport process.

I had both Cisco VPN and Checkpoint installed. Since removing Cisco's client and reinstalling Checkpoint's, the Airport process still shows up in the Activity Monitor, but only for a couple of seconds, then dissapears. Thus it would appear we have found the problem and solution, at least some more things to try...

I uninstalled CheckPoint SecureClient and reinstalled, and so far I too have had no runaway airport process problems either.
