vmstat Output Is Incorrect After Configuring Processors (Bug ID 4159024)
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 r b w swap free re mf pi po fr de sr s6 s9 s1 -- in sy cs us sy id 0 0 0 437208 146424 0 1 4 0 0 0 0 0 1 0 0 50 65 79 0 1 99 0 0 0 413864 111056 0 0 0 0 0 0 0 0 0 0 0 198 137 214 0 3 97 0 0 0 413864 111056 0 0 0 0 0 0 0 0 0 0 0 286 101 200 0 3 97 0 0 0 413864 111072 0 11 0 0 0 0 0 0 1 0 0 4294967216 43 68 0 0 100 |
Workaround: Restart vmstat.
