I found that out, thanks!

Using rpctrace I get the same output as you. It seems like the
SCM_CREDS support is failing somewhere. Or the implementation differs
from the kFreeBSD version.

And using gdb does not work, something in the latest gdb is buggy:
/build/gdb-N8gCcv/gdb-7.10/gdb/inline-frame.c:167: internal-error:
inline_frame_this_id: Assertion `frame_id_p (*this_id)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
