PM88845: RDZ V7625 LOGON FAILS WITH EDC5140I BROKEN PIPE

APAR status

• Closed as program error.

Error description

• RDz v7625 logon fails with EDC5140I Broken pipe
  

Local fix

• this problem is caused by serious delays in logon processing.
  This can be network delays, but more likely there are threadpool
  problems, where a threadpool accepts a logon but then fails to
  process it.
  A second connect attempt will be directed to a different
  threadpool and will be successful.

  ****************************************************************
  01.In RDz Daemon, logon sometimes took so long that the client
     timed out and closed the socket. This lead to the Broken pipe
     message encountered by the RDz daemon.
  

Problem conclusion

• 01.Now, RDz Daemon monitors the client connection and if closed,
     RDz will not send any data to the client.
