rb600 rebooting in bandwith test

my first test test dual-nstreme with RB600


PC—[lan]----RB600-1 …[nstreme-dual]…RB600-2

-set only nstreme-dual on 2 CM9 cards(2 in each of RB)
-LAN a NSTREME interface in bridge
-tested in office 20m between units
-MT v.3.0
-power supply: 30W MT 48V

If I run bandwidth test on PC (as BW server) and i Run BW test on RB600-2, with TCP sending after while RB600-1 reboots. If I try do this again, it reboots again…

any idea why it is rebooting?

thanx
