I am occasionally and not reproducibly getting this error: ERROR: sum weight for constraint 0 is zero It is emitted by parmetis. My code passed valgrind reasonably well. Well, the input mesh could be invalid in some way or another of course (even when I do not think so), but then the error should be reproducible, while it is not. Does anyone have an idea what can cause it and how to prevent it? Many hanks for any hints, Dominik
