Does anybody have an idea why the second cpu is not used for the
computing intensive work?
idle will stay around 50% while the two instances of python2.4 share 1 CPU
The only unusual occurence recently were a few Bus Errors and the system freezing
when two processes which were using around 2-4GB of memory each were running
