APAR status
Closed as program error.
Error description
If the Queue manager associated with a multi-instance integration node goes down then the standby Queue manager in the secondary node immediately become active. The integration node running as the active instance detects that the QueueManager is down and so it attempts to stop all the integration servers associated with it and once all the integration servers stops the fail over completes. An integration server get stopped only after all the active transactions of the message flows completes. In some scenarios an active transaction can take a very long time preventing the fail over to complete on time.
