- the Event is offered to the Queue
- each Worker thread has its own Selector and a DB Connection
- the Worker thread takes the Event from the Queue, sets the Selector and the DB Connection in it and calls Event's method getProcessed
- the Event reads the SocketChannel (always fine), queries the DB (always fine) and writes to the SocketChannel (works under Windows and fails under Red Hat)

When it succeeds and when it fails, the log is always perfect:
