Error description

• The mq-qm state machine may stop if there are more than 2
  events transiting the same mq-qm object to down at the same
  time.
  For example, there are more than 2 connections established for
  the mq-qm. When the network suddenly goes down, both of the
  connections break and then transit the mq-qm to down at the
  same time. In this case, the mq-qm state machine may stop. It
  will need manual restart the mq-qm object to reactivate.
  Only these or later firmware version are affected:  7.0.0.17,
  7.1.0.14, 7.2.0.11, 7.5.0.5, 7.5.1.4, 7.5.2.2
  

Local fix
