I have created Stat machine VS WF. It has 6 different stats two stat has back and forth. It is working fine in DEV environment(Win 2008) but It get stuck in 4-5 stage in Production environment. Currently assumption is because it is giving Due to heavy load, the latest workflow operation has been queued. It will attempt to resume at a later time. after one or two items creating. However same error Due to heavymessage I am getting in my DEV environment but Workflow is totally working fine in DEV.

The workflow Stage is not moving for few minutes when we got this above message in both the environments, then after few minutes...it is going to next level.

The same time we check the ULS logs and find below one most frequent error.

Engine RunWorkflow: System.Workflow.Activities.EventDeliveryFailedException: Event "OnWorkflowItemChanged" on interface type "Microsoft.SharePoint.Workflow.ISharePointService" for instance id "e2664350-24ad-411e-8092-6e81ca5b0af0" cannot be delivered. ---> System.Workflow.Runtime.QueueException: Queue 'Message Properties  Interface Type:Microsoft.SharePoint.Workflow.ISharePointService  Method Name:OnWorkflowItemChanged  CorrelationValues:  e2664350-24ad-411e-8092-6e81ca5b0af0  ' is not enabled.

I went through below suggestion from the forum which is not helpful to me at this moment

I tried to find the solution on internet and done as per the suggestion but not worked at all.

• Increase Throttle Size
• Increase Batch Size
• Time Out
• Workflow Timer Interval

Another interesting thing is, I am writing logs when any task created or changed. I am not able to find the task related log(creation or change) in delaying because of Due to heavymessage even after few minutes task changed or created event ran and created new task or changed the task.  

I got stuck in this issue since two weeks but there is no any clue or suggestion. I really appreciate any help.

Thanks in advance

Hi Pritesh,

may i know what is your latest sharepoint cumulative update that you have at the dev and prod environment?

i check at december 2012 cumulative update there is an update regarding this.

another thing that i would like to check, do you have any time pause steps on your workflow?

Hi Aries,

Thanks for looking into it.

We have June 2012 CU in Prod and OCT 2012 on my DEV. There is no pausing activity in Workflow.
