With (3) DN3500s running SR 10.1, I have seen this problem
several times when doing an "ls" with options from one 3500
to another or from a 3500 to our DN10000.  The problem only
occurs in directories that do not contain user accounts (i.e.
it does not occurr in /u1 on our machines, but everywhere
else like /etc and /usr).  

The bottom line is that there is a bug in the file /sys/ethernet8_microcode.
The solution is to rename the file to /sys/ethernet8_microcode.old and
let the communication services use what is in the ROM on the ethernet
controller.  There is also a patch version of ethernet8_microcode
available which I have, but I have not bothered to install it as the
performance difference is negligible and I don't want to push my
luck.  This is a well-known bug within Chelmsford, and I think it
has made it to "technical bulletin" status.

As a secondary curiousity, I would also check to see if Unix
restrictions are enforced in your registry, but I'm sure what
I suggested above will do the trick.

P.S.  I am referring to /sys/ethernet8_microcode on your DN3500's and
DN4500s, you won't find this file on the DN10000.
