Error description

• EMS messages like:
  21-08-17;10:06:08.170 \CS3.$X0Z3M    TANDEM.TMF.L02
   NonStop TMF on \CS3 *0396* TMF Library Process

   From Gateway is being processed. BCB State is Terminated.
   TransId Nil. TcbRef Nil. TMP Rm Id: -1 $TMP.#RV00010.
   This is an Open-Tmf anomalous condition. There may be some
   in-doubt transaction branches.
  can be seen, where the process id resolves to an amqcache
  process.
  

Local fix

Problem summary

• IBM MQ V8's amqcache process uses certain OpenTMF calls
  as an action to transaction events.
  This can lead to the seen ems message.
  

Problem conclusion

• The product has been changed to make amqcache proceses
  not use these specific OpenTMF calls anymore, preventing
  the message from being generated.
