      Steps to reproduce:

      1. Send more trapper items than preprocessor can handle
      2. Watch the preprocessor queue grow, and the master processes CPU grow with it (expontential?)

       

      Result:

      1. the queue grows, proces
      2. Processed items (per iteration) shrinks and CPU consumed by the manager increases.

      Expected:

      1. Queue length should be limited
      2. Preferably the queue should scale better
