| The attempted FD is #18, but the error just | says "1", not "18": I am still looking for the source of that error message, I suspect finding that and seeing what sys call is actually generating EINVAL will provide a huge clue as to why this fails for you, but normally works. Thw 1 is probably becausr is is stdout (fd=1) being redurected. kre
