My machine has recently had trouble with getting work units (snippet of log below).
This is typical of performance before the work units stopped:******************************* Date: 2016-03-11 *******************************

I wondered if there might be a lack of units for 32 cores so I implemented multiple slots of 12, 12, 8, leaving the initial slot set to -1. I immediately got work units, however the PPD appears much less than before.
Could somebody please help me work out what's going on and, if possible, how to resolve it. This machine, unlike my others, is dedicated and so I'd like to use it for the maximum benefit for the folding project. I'd appreciate any input on config.
Thanks very much.
