Hi Sean, It looks like you are not using the standard regex file: > SectionsBsv=E:\ctakes\apache-ctakes-4.0.0\DefaultSectionRegex.bsv
Is it possible that there is a poorly-formed regex? The sectionizer should time out any regex that takes longer than a few seconds to complete, but it is possible that something in the timeout isn't working. As an aside, I don't see a sentence annotator. A whole lot of downstream annotators depend upon sentences, so you should add one.

Without the sectionizer added, I get ~1000 documents/minute. With that line added, I ran the pipeline for an hour and got no documents annotated. Can anyone suggest what's going wrong here and how to fix it? FWIW I created a .xml descriptor file and tested the sectionizer and .bsv in the CVD and it worked as expected with only a small-moderate decrease in speed.
