questions about periodic

[Jonathan Horne]

i have a couple virtual machines running freebsd 6.1-;4 on a ms vs2005 host, 
and as of the moment of this writing (and for a while now actually), they are 
idling at near 0% utilization.  but during the nights, they really get going 
to the point that they ramp the cpu fan speeds to max on the my host box!  it 
takes them hours and hours to quiet back down, sometimes not until i power 
the virtual machines off and back on again.

im wondering if the cause of these early hours cpu hogging could be comming 
from items running from periodic?  i think the daily folder is probably the 
culprit.  is there a good way to see which all scripts are being run, what 
their scheduling and priority is?  i would like to cull out as many as i 
could live without (if possible).

thanks,
jonathan
