No, I didn't explicitly. But I killed nearly every process but the kernel
threads and it didn't change. Shortly before rebooting the load even rised
again without me doing anything - very creepy (I thought about a rootkit but
the machine just has a NATed ssh port open to the internet on a non-standard
port).
uptime is now 6:32 and it has not happened again.
