IC68925: WMQFTE V7 PROTOCOL BRIDGE AGENT STARTS TO LOG BFGIO0134E FOR EVERY SCHEDULED TRANSFER AND TRANSFERS DO NOT GET SENT

APAR status

• Closed as program error.

Error description

• When a WebSphere MQ File Transfer Edition (WMQFTE) v7 bridge
  agent transfer is canceled, the bridge resource is not
  recovered. After about 50 canceled bridge transfers
  the protocol bridge agent starts to create an FFDC log file
  with message BFGIO0134E, for every scheduled transfer, and
  continues to do so until it is stopped. Any new files that
  appear after that point are not transferred until the bridge
  agent is restarted.
  The BFGIO0134E FFDC log file shows:
  Cause:      com.ibm.wmqfte.io.FTETransferIOException:
  BFGIO0134E: An   internal error has occurred. There are no
  available bridge sessions to process transfer 12345...
  ADDITIONAL KEYWORDS: WMQ FTE scheduled transfers
  

Local fix

• Restart the WMQFTE bridge agent using fteStartAgent
  

Problem summary

• A protocol Bridge agent leaks FTP containers in certain
  circumstances, such as a nuber of transfers being cancelled:
  This results in an FFDC being generated with the following
  information:

Problem conclusion

• CONCLUSION:
  A WMQFTE transfer which has one (or both) ends is a bridge agent
  is allocated a bridge container to handle all transactions with
  the protocol file server. These containers are returned to the
  pool on completion of the transfer. However, if the transfer was
  cancelled or had failed (for example remote end disappeared)
  then the transfer would have been terminated, but the container
  was not returned to the pool. Once all the containers have been
  used up (~50) future transfers will be rejected with reason code
  "BFGIO0134_NO_SESSIONS".
