APAR status

• Closed as program error.

Error description

• A service using a MQ backend falls into an infinite error
  reporting loop when having trouble connecting to the backend due
  to the TCP connection not timing out.
  

Local fix

• If the DPMQ/DPMQFTE URL-Opener's timeout parameter is greater
  than60 seconds, the backend timeout should be greater than
  the timeout parameter in the DPMQ/DPMQFTE URL-Opener.
  

Problem summary

• Affected is the use of the DPMQ/DPMQFTE Protocol URL as the
  backend of a Multi-Protocol Gateway or Web Service Proxy
  service.
  
  
  If a network error occurs, DPMQ/DPMQFTE Protocol URL might not
  react to the network error immediately.
  

Problem conclusion

• Fix is available in 5.0.0.14, 6.0.0.6, and 6.0.1.2.
