It's the number of _active_ processes. Or to be more precise it's the 
number of processes waiting in the queue to get scheduled to execute on 
the CPU. You cannot get a 3.0 load average with all processes being idle, 
so something is definitely abnormal. You need 3 processes loaded at 100% 
to reach a load average of 3.0 (with 1 CPU).

But I'm curious if opensips can really trigger this, or is just a glitch 
in the OS reporting the load average?

An interesting piece of information would be to know if the opensips 
processes have any incoming/outgoing network queues (seen with 
netstat -pan | grep opensips).
