I am facing a really strange issue. I have two workflows designed for a document library where first workflow runs on item creation. First workflow is designed to trigger the second workflow. The workflows work as expected if i upload a single document at a time. But if documents are uploaded in a batch (e.g. a batch of 10 or 20, through some external system), the workflows are not even initiated for the first document in the batch, whereas, workflows are at least initiated for rest of the documents in the batch. what can be the cause of this issue. Any help/suggestion would be greatly appreciated.
