Many Activities are getting created for a failed Inbound email message while processing

Hi,

We have 'eMail Response - Process Message' deployed to handle incoming responses from users.

Whats happening with this is - when this workflow errors out while handling the responses, I see in Workflow instance Monitor, re-process of the same workflow instance getting submitted for every 5 min to process it again and getting errored out again(since it errored out first time). As you must aware - an activity record gets created in 'eMail Response - Create Activity' step while processing. Due to this, many activity records are getting created for the failed one and is DB size is increasing day by day.
