The way we (Lynx Analytics) use RDDs, this affects almost everything we do
in production. Thankfully it does not cause any issues, it just logs a lot
of errors. I think the adverse effect may be that the memory manager does
not have a fully correct picture. But as long as the leak fits in the
"other" (unmanaged) memory fraction this will not cause issues. We don't
see this as an urgent issue. Thanks!
