Workflow fails in Server with Error: InboundNamedPipe GetOverlappedResult

5 - Atom

I have a workflow reading from Multiple sources (DB, excel) and outputs to .xlsb file. There are 4 tabs in .xlsb file. This workflow works perfectly fine in designer but fails in server with error : InboundNamedPipe GetOverlappedResult: The pipe has been ended.

I tried to debug step by step to pin down the spot in workflow. I am using block until done to write the 1st tab , once complete it flows to subsequent tabs. I deleted the 1st tab wing at the BlockUntilDone branch. It ran fine in the server. When I introduced the 1st tab it failed again. With my research with this error I understood there can be many issues with this generic error. So I changed Datetime column to Date/vstring , no Int64 columns. I am still stuck. It is been almost a month that I am trying to fix this. what am I missing?

I have 4 other workflows with almost similar structure with different filters and they all work fine in server. 

Can someone help me? Thank you
