The 4DDN release level was not mentioned, but the 4DDN system hang problem
sounds familiar. There was a serious problem with the 3.1D 4DDN kernel 
getting into a state where mbufs were being consumed but never freed. This
memory leakage eventually caused the system to hang. The bug has been fixed
in 3.1G, 3.2, and 3.2.1.
