Symptom

When running show system resources from the PAN-OS CLI, the top process in the output shows 9999% CPU utilization.

The following is an example output:

> show system resources

top - 09:41:01 up 11 days, 14:40,  2 users, load average: 0.00, 0.00, 0.00

Tasks: 138 total,   3 running, 134 sleeping,   0 stopped,   1 zombie

Cpu(s):  0.2%us,  0.1%sy, 0.0%ni, 99.7%id,  0.0%wa,  0.0%hi, 0.0%si,  0.0%st

Mem:   4055392k total,  3643912k used,   411480k free,   366956k buffers

Swap:  2007992k total,        0k used,  2007992k free,  2340368k cached

  PID USER      PR NI  VIRT  RES SHR S %CPU %MEM    TIME+  COMMAND

    3 root      RT 0     0    0 0    S    0  0.0   0:06.82 migration/0

    4 root      20 0     0    0 0    S    0  0.0   0:00.00 ksoftirqd/0

    5 root      RT 0     0    0 0    S    0  0.0   0:06.78 migration/1

    6 root      20 0     0    0 0    S    0  0.0   0:00.00 ksoftirqd/1

Cause

The 9999 value is seen on occasions due to an incorrect calculation performed by the show system resources (same as Linux "top") command. The correct output will be displayed by reissuing the command several times. In the example output above, the correct utilization values are shown in the upper section of the display, where load average shows 0.00 and cpu information shows 99.7% idle.
