Thank you Lukas for your reply.
As i said we are not using Broker or UM. we are using IBM MQ connecting using JNDI/JMS configuration and JMS Trigger. and I am facing the same issue as yours in UM.
“Trigger from 2nd node is picking messages from JMS/MQ even though node One trigger just called the service which is still running”
I did the same thing what you said, disabled the trigger on one node so that records gets picked up only on other node in the cluster.
Any thoughts on, if using IBM MQ instead of Broker/UM.
Thank you,
