      Description

      Observing strange CPU activity occuring at regular (seemingly fixed) interval with no protocol traffic activity.
      See attached window capture of task manager that shows this with 3000 active connections.

      Is there some kind of cleanup occuring within MINA core at a predefined interval?

      The 3000 connections in the example above connects within 250 seconds. A normal situation would be that these connections are established over a longer period of time, perhaps spreading the CPU peaks shown above as well, flattening the curve.
