Hi all,
We use MIPS Linux+uClibc0.9.28+busybox 1.1.0 on our machine.
After use "uptime" to get the loading of device, it shows:
03:50:05 up 3:50, load average: 2.00, 2.00, 2.00
Is it normal? It seems too high because my PC Linux has a much lower value:
20:38:31 up 12 days, 5:11, 5 users, load average: 0.04, 0.01, 0.00
Regards,
Colin

Well, check with ps what is causing the load. Look for processes in
either 'D' or 'R' state.

Hi Ralf,
Here is the result:
/usr/local/bin # ps -aux

/usr/local/bin # uptime
00:19:29 up 19 min, load average: 2.00, 1.95, 1.41
The uptime value keeps on going higher and higher.
It seems that both 646 & 647 process has the same parent "1".
Their "utime" are "0".
Thanks and regards,
Colin

Yes, these two are the offenders. A process should never be for a long
time in "D" state. You'll have to figure out what these processes are
doing, but they something wrong with these two.
The load average btw is a fairly artificial meassure. On a properly
working system it describes the burn of the workload of the system
reasonably well - but if things go wrong and cause processes to get
stuck in D state (aka uninterruptible sleep) then a system may well
still be perfectly responsive even though the load is very high.
