Avoiding OptimisticLockingException when receiving a message event during job execution

[hassang]

Hi @fredrikw

Try modeling it as stated in below post

Message Correlation Exception in Receive Task

This can happen some times with fast messages. You’re pretty close to the solution. Using a parallel gateway is the first step but then you need to make sure to create a “wait state” before sending the message by ticking the “async-before” box. This will ensure that the engine starts waiting for the reply before sending the message [image]
