 System information disabled due to load higher than 1

That's what I usually see on this 10.10 box. Yet the load is less than 0.5 even during the login procedure.

Any ideas? This is not the only server this is happening on and asking on IRC I am not the only person observing it.

I just adjusted the script to read "if [ $(echo "`cut -f1 -d ' ' /proc/loadavg` < 2.0" | bc) -eq 1 ]; then" but it still happens.
