Description Arthur Dent 2011-06-29 09:46:02 CEST
Description of problem:

i noticed on my mageia box (64bit, single core cpu) that the load average is nearly constantly at 1.0/1.01/1.02 BUT - the cpu load monitored using top or htop does not really change from 0.5% to 2%.
This machine sits normally idle being used for mageia tests or, its main purpose, serving as a squid proxy.

Accessing the machine through requests to squid gives the mentioned 2% cpu load, just monitoring it using top/htop in a terminal window (ssh) gives a load below 2% (ususally around 0.7%)

As far as i understand, the values of the load average should then be somewhere around 0.something, but never around 1 (for the one minute/5 minute/15 minute load average values) unless the machine is really under heavy load.

The values at
cat /proc/loadavg
displays
1.19 1.06 1.04 2/196 20759


A 'ps agux' gives the following output, 
for me there is nothing unusual with the processes (the machine is indeed idle).
I did have the same configuration in mandriva before, the load average was 0.something as expected and in no way similar to the mageia output.
