- Jason,
-
- We ran into this problem before and had to talk to Hp about it.
- Hp told us that the number was so high that when the CPU converted to decimal,
- It became negative. The number stands for priority, the higher the number, the
- higher the priority. So when you see a process with a negative 'C' number, it
- means that that process as gone crazy and is sucking up the cpu time causing the
- system to be real slow. Take a look at the "TIME" column. That should be very
- high when this happens.
