@brollb I am conceptually stuck on what this block should do. My latest thought is to treat it like a Javascript block, i.e. to allow users to put arbitrary SPARQL...

A guess is that a student might have copied the code for the server, creating an infinite messaging loop.

Yes, we stopped the project and restarted to restore the functionality. My user name is andersoncliffb and we were working on the project ~10:30 a.m. on Tuesday, March 19th. Thanks...

Yes, it was. Thanks again.

OK, good suggestion. If I see this happen again, I'll report the bug using the built-in mechanism.
