It's a known issue, and there's a patch in the works. The problem is that the calculation of load average is done via a softirq, which in vanilla Linux is not a thread (nor an RT task). But in RT, all softirqs are RT tasks, and when this calculation is performed, it sees that there is always an RT task runnning. That RT task that it sees running happens to be the softirq RT task that is calculating the load! So the numbers are bogus! -- Steve > root@xxxxxxxxxxxxx:~# cat /proc/loadavg > 0.00 0.00 0.02 1/52 1159 > root@xxxxxxxxxxxxx:~# > > I am curious: > 1.
