Are you sure the CPU usage is high?  I've seen something like this before 
where the load average suddenly spiked up but the actual CPU utilization was 
reasonable. No, I can't explain how that could happen, but that was what I 
observed.  It did seem related to timing out on VL servers.  What OS are you
