Error description

• RDz v80: add additional heap usage tracing
  rseserver.log
  When the heap usage is over the value specified by
  maximum.heap.usage.ratio, the heap usage will be logged once.
  After that, the heap usage will not be logged even when the heap
  usage is over the maximum threshold:
  INFO Over MaxHeapUsage: ProcessId=, Memory_Usage=
  
  When the heap usage become below the threshold after the heap
  usage was over the threshold, the heap usage will be logged
  once:
  INFO Below MaxHeapUsage: ProcessId=, Memory_Usage=

  * PROBLEM DESCRIPTION: 01.There is not enough trace to show    *
  *                         why a new threadpool server is       *

  01.There is not enough trace to show why a new threadpool server
     is started.
  02.RDz client sends a client certificate to the server but the
     server fails to read the certificate due to a timing issue.
  

Problem conclusion

• 01.When the heap usage is over the value specified by
     maximum.heap.usage.ratio,the following trace will be logged
     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
     server.
