I have been getting a bunch of these, related to SWP views. I am not doing
anything special. My SWP SPARQL queries, and the views, test out fine in
test cases and live, when they load. I also get a lot of timeouts on the
views. Very weird, and frustrating.
Also, when these errors occur, it seems as though topbraid is caching a lot
of memory because the memory footprint grows to the max I have allocated
and then it churns away on something, using a lot of cycles, until I give
up and close the application. Before all of this happens it is 'fine'.
