Are any of your hier blocks written in c++? If so, are you trying to intermix in any of these such blocks both a flowgraph as well as ‘work’ of any kind? Although one shouldn’t be able to create such a hier block — their intent is just to encapsulate a flowgraph — the GR API allows one to program this dual use block. The c++ will compile, but it will fail runtime execution . I don’t recall the exact error message, but it’s something like what you reported , hence my wondering. We should really get this fixed in some forthcoming GR release. Hope this is useful! - MLD

I am only a couple days into this, with a project that has several heir blocks.
I just started getting a message "port number 0 exceeds max of (none)"

I've looked through my files, and I don't see any unconnected ports.
I don't see anything that indicates even which file or heir block is causing the problem.
How can I track this down?
