EHSM 2.0 Action workflow did not trigger occasionaly

Hi

We have issue around workflow for Incident action. I have seen few post. There was one from Bhuwan having similar workflow for action item not triggering. We are on EHSM200 SP002. Checked SLG1 log and getting "Error while attempting to clone BO template for setup 2478" In our process the action item triggers automatic on completion of investigation & also it is random. Only around 5% action item did not get workflow.

Upon manual action added and put in process works fine.

Can anyone put some light on it

thanks
