       once
       INFO Over MaxHeapUsage: ProcessId=, Memory_Usage=
       When the heap usage become below the threshold after the heap
       usage was over the threshold, the following trace will be
       logged once:
       INFO Below MaxHeapUsage: ProcessId=, Memory_Usage=
    02.RDz server must wait for the client certificate to reach the
