The difference between slave01 and slave02 here is the "idlcachesize 15000" line. We added it to slave01 last week, and I did the 6 am LiveUP to add it to slave02 today. Looks like that is a step in the right direction.
Have you looked at the monitor backend to see how full your IDL cache is then? Perhaps you may want to increase it additionally. Knowing how full it is can help give you an idea of that.
