Hi;

I have a scene file that generates some procedurally-generated geometry based on top Wedge attributes. I use a ROP Geometry Output TOP to write each bit of geo to disk, before continuing on down my PDG graph to render the geo.

I notice that maybe half the time (this is a very rough estimate), the ROP Geometry top seems to "hang"; it save out one or two bits of geo, but then just seems to stop doing work. Left un-interrupted, Houdini can stay in this hung state for hours. This is all being done via Hython, so I usually have to kill my Windows shell and restart the process. I can't identify a pattern that causes it to hang sometimes and not others.

I've set my localscheduler to just use 1 slot, and my ROP geo node is set to run in-process. I can't imagine what about this might be causing this hanging; curious if anyone might have some advice as to how I might troubleshoot?
