fstat on Pinebook

[Alexander Nasonov <alnsn%yandex.ru@localhost>]

On my Pinebook fstat prints some errors and no output:

pinet# fstat
USER     CMD          PID   FD MOUNT       INUM MODE         SZ|DV R/W
fstat: can't read dtab at 0x0 for pid 977
fstat: can't read dtab at 0x0 for pid 792
fstat: can't read dtab at 0x0 for pid 1
fstat: can't read dtab at 0x0 for pid 0

Processes 977 and 792 are ksh shells.

Is it only me or a common problem?
