It has been for me. I opened Console and it said that the last 5 crashes were due to the presence of Cisco AnyConnect software installed. I had a friend give me version 3 so I have been trying it. Well I didn’t have a VPN session going when it crashed, but the module was still loaded and it was indicated as the problem.
So I have uninstalled the program using the Cisco Anyconnect uninstaller and restarted the machine. I am trying to recreate the crash, but what I have done in the past to create the crash has not triggered it. Have I found the solution for you?
Other research at the Apple forums said it was the system UI server. This was a problem in Snow Leopard too, and seemed to be fixed then by throwing away the UI preferences. You can throw it away by going to your own user folder ~/Library/Preferences/ByHost. Throw away that entire folder. I am going to do that if it crashes again.
Apparently some users have had problems with Cisco AnyConnect Software and 10.6.8. It seems that after installing the newest OS, that CAC has problems getting and staying connected. This software has had problems for some people for several years, and here are some solutions to fix them that have worked for others.
Upgrade your version of Bonjour or disable it. This can be a problem for machines that are 10.6.3 or earlier.
Use Ligion to restart the Cisco VPN service. Google this term and you will come up with the command used for this.
Uninstall and reinstall the software. This seems to fix it for some people.
Disable third-party software like Anti-virus software, firewalls or programs like Little Snitch.
Disable or better yet, uninstall old versions of Cisco VPN software.
ARogan: PS3 Hard Drive Upgrade and Yellow Dog Linux. Interesting that they chose YDL. I tried it on a PowerPC mac many years ago and it worked but it wasn’t very useable. I wonder how many PS3 owners are using other operating systems on it?
VMware KB: Sharing a virtual machine between users in Mac OS. Nice step by step on how to accomplish this. It may not be a good idea to do this in practice however. I can see the situation where the security of the VM is compromised and it isn’t clear whose responsibility it is.
