Kernel Panic in SANDPOINT 5.99.64-GENERIC on DSM-G600

[Charles Brown <obigiankenobi%gmail.com@localhost>]

Hello,
I'm experiencing a kernel panic on my DSM-G600 rev.B2.
1) Enable ftp server via inetd in /etc/inetd.conf
2) Connect via ethernet the DSM-G600 to a PC (my linux machine).
3) Create a 1GB file using: dd if=/dev/zero of=1giga bs=1024
count=1000000 in the linux machine.
4) Connect to DSM-G600 via ftp and try to send him 1 giga using: put 1giga
Few seconds e...:

I tried also ftp get to DSM-G600, same result (build of the 1giga file
using dd on DSM-G600 works fine, so I think that is not a disk issue).
This happens every time.
Could someone try to reproduce and confirm this?
Thank you very much.
