Microsoft.ServiceBus.Messaging.SessionLockLostException

Hi -

We have workflow manager 1.0(CU2) and service bus 1.1)(CU2) installed on a  Win2k8R2 On-premise SharePoint 2013 farm. Workflow manager has been  installed on 3 SharePoint servers  in App layer .

Issue: We are observing intermittent errors like below in the event log on any of workflow server and it is happening in Pre-prod and Prod too . When this happens, the current workflow suspends and re-triggers a duplicate workflow for the same instance which resulting data corruption with duplicate instance as per our application functionality design . 

Error message :
