Since yesterday (perhaps some system updates), the Cisco AnyConnect VPN makes the system freeze when I try to connect. It looks like a memory leak, since the memory used goes up to 90%. I am using Kubuntu 12.04.


I removed the file cert8.db from the ~/.mozilla/firefox directory and now it works again. I am not sure why this happened. The inspiration came from another problem I had long ago with the same client.
