uptime, top, cat /proc/loadavg all reporting load averages for the last 1/5/15 minutes as 0.00, but the system is definitely busy doing work. Why is this? Server is running Red Hat Enterprise Linux Server release 6.6, kernel 2.6.32-504.12.2.el6.x86_64.

$ uptime
 12:13:44 up 73 days, 8 min,  1 user,  load average: 0.00, 0.00, 0.00

$ cat /proc/loadavg
 0.00 0.00 0.00 12/2706 39700

$ top
top - 12:15:35 up 73 days, 10 min,  1 user,  load average: 0.00, 0.00, 0.00
Tasks: 572 total,   4 running, 568 sleeping,   0 stopped,   0 zombie

Load averages only account for processes in the running state and the values may very well be under 0.01. More details here: https://stackoverflow.com/questions/11987495/linux-proc-loadavg

A bug is also a possibility ;)
