Without seeing your query, I can't be sure, but I bet you're doing nothing wrong, except apparently not noticing that result sets are limited in size and that queries are limited in execution time. This is necessary on a universally accessible server, to prevent Denial-of-Service attacks and the like. I can't immediately think what utility you might get from the exhaustive list you're requesting -- so I will first suggest that you build queries to work with a smaller expected result set. If you really do need *every* ChemicalCompound in a single result set, you probably need to get your own DBpedia instance running, so that your subsequent queries don't block (and aren't blocked by) queries made by other users. There are a few ways to get your own instance going. The fastest is by using the Virtuoso AMI for EC2 [1] with a DBpedia restore, as released by OpenLink in December. Of course, you can also download all the component data sets and source code, compile your own Virtuoso binary, and load all the data in -- but this takes many more hours, and has much more potential for errors and back-steps along the way.
