It runs nicely in newer kernels (5.11.12-1-default > openSUSE and 5.10.0-6-amd64 Debian).

There doesn't seem to be anything kernel related that would affect anything there so I cannot think why on older kernel would make a difference. Or an older rpcbind... Maybe I'll experiment on a SLE12 kernel. NeilBrown
