vmstat Output Is Incorrect After Configuring Processors, Bug-ID 4159024
Category: Bug
vmstat shows an unusually high number of interrupts after configuring CPUs. With vmstat in the background, the interrupt field becomes abnormally large (but this does not indicate a problem exists). In the last row in the example below, the interrupts (in) column has a value of 4294967216:
| # procs memory page disk faults cpu |

Workaround: Restart vmstat.
