I have two ASA 5520's running 8.0(2) and ASDM 6.0(2). Ever since I upgraded I've had issues with ASDM when using the Real-Time monitor, it pegs my PC processor at 100% and locks up ASDM. I guess it could be my machine, but I never had an issue with the other versions. Anyone else had similar issues or is there a fix available?
