Problem summary

• ****************************************************************
  * USERS AFFECTED: 01.All RDz users                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: 01.The client could not connect to the  *
  *                         remote system at all.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  01.When RDz Daemon receives a new connect request, the Daemon
     sends the connect request to the threadpool process.
     When the threadpool process does not send back a new socket
     for the client logon in a definite time, the daemon process
     marks the threadpool process as timeout status.
     When the timeout occurs, the Daemon tries to send a data to
     the threadpool monitor thread and the Daemon process resets
     the timeout status if the threadpool monitor sends back ack
     to the Daemon process in a definite time.
     But the main thread in the threadpool process hung but the
     threadpool monitor thread is running normally. In this case,
     the timeout status is reset but the timeout occurs again when
     the Daemon process tries to send a new connect request to
     this main thread of the threadpool process.
  

Problem conclusion

• 01.Now, when the timeout occurs, the Daemon process tries to
     send data to the main thread of the threadpool process to
     examine whether the timeout condition is solved.
