Hybris business process in running state

The order confirmation email did not get triggered after placing an order. Looking at the business processes for the order, none of them got triggered.

Things I check-listed:

• Restarted admin node
• Deleted all business processes that are in running state
• Looked for any failed feed in the hot folder
• Had a search for TaskExecutor-master in Hybris thread dumps - to identify which part is causing an issue, none found.
• The task.engine.loadonstartup = false.

None of the above worked.

Please help me resolve this issue.

**Solved:

We had an issue with the cluster ID. All the nodes had the same cluster ID. This was caused due to a wrong deployment. We re-mediated it which fixed the issue.**
