CPU%sy overloaded by D processes

[Penteado]

Hi there,

i have a server that is having a strange behavior while managing game processes...

The %sy is going wild over 60% when a bunch of CS(Counter Strike Game-servers) processes kicks in D state ... As you can see in the result of the top command, there are many processes that has the D state. When i kill one or two the server goes normal.
I also noticed that some processes has the same value on the SHR(shared memory?) column, if they share memory is it possible they go into a deadlock?

How do i script something that kills automatically D state processes? is it possible ?
