Is there somewhere in NetSuite that you can see a processing que for workflows, I have a scheduled workflow that never runs on time. In fact, today, the workflow has not run and it has been over 2 hrs.

Not exactly a "processing queue" but you could run a Workflow Instance saved search that would show all the instantiations and current state of whatever workflow(s), if that would work for your use case

That worked, it turns out that someone modified the search used in my workflow and it was returning 0 results.
