No crons running.
We're on a VPS so we have are own allocated services on a shared server, so in theory we shouldn't be affected by other user accounts - that's the theory anyway
We seem to be getting a bad hit for about 15/20 minutes, and are load averages go right up, then suddenly everything is back to normal for 6 hours.
Everytime we get in touch with support, they just show us the load averages after the storm when everything is back to normal
