As the title says, the mpstat command, executed on Slack 13.0 continuously shows almost no processor utilization of any sort. In fact none of the output ever seems to change at all. The system is dual processor board with two hyperthreaded P4 Xeons. Any ideas?

This is, literally, the only output I can get from the program. No values change ever.
