I am processing documents and invoking workflows to move through the process and when I get to the end, I invoke the starting process to move to the next batch.  After a few hours of running, my process stops because the maximum invoke depth has been reached.  I see in Workflow Error 0700-WF10 with "Invoke Workflow" Activity that the limit is 32 to prevent runaway workflows but if this is not a runaway workflow, how can I work around it?

My process is this:

Workflow A - Looks for Documents in processing folder.  Invokes Workflow B on any found documents.  Waits for process folder to empty.  Invokes Workflow C and then ends.

Workflow B - Process document and move it into archive structure.

Workflow C - Assembles batch of documents in processing folder and then invokes Workflow A.  If it finds no documents to assemble in the processing folder, it ends without invoking anything else.
