I have a workflow (2013 - On Prem) that queries a large list, and writes all records from the previous month to a CSV file then PUTs the file in a library via the Web Request PUT method. When testing with small record sets, everything works fine. The production use of this will write about 5000 records to the CSV.
When looping (For Each Action) through the collection variables and writing each field value to the Build String action, the workflow fails part way the process. After about 5 minutes of looping, the process just stops with no explicit errors. the only error is "BackUp Easterner Status Records failed to start". Mind you, it has definitely started because verbose logging shows that it has progressed quite a way into the process. It is not failing on a particular record either. Some times it will write a few hundred records and sometimes it writes just over 100.
Does anyone have any ideas as to what the problem may be?
Thanks and Best Regards,
