VMSTAT and MPSTAT anomalies
All:
I have a V445 server with four IIIi CPUs and 8 GB RAM running Solaris 10 and an Oracle database along with some app server components and we have had some performance issues - so I collected some VMSTAT and MPSTAT data over the course of three days with a 15-minute polling interval.
I have been looking over the data and I gotta believe that there is a bug becasue I had both VMSTAT and MPSTAT report values in excess of 20.495 QUADRILLION system calls / faults (vmstat faults:sy, mpstat xcal & mpstat syscl - see below).

Has anyone EVER seen values this high before? Are these numbers even realistic or is this a bug????
Many thanks in advance,
Jeff
