new software on the server, ..., almost done

[Carter Bullard]

Well, it looks to me that we tried to malloc() for a user buffer,
and malloc() returned with NULL.  We usually would die at this
point, but i didn't put a stop here for the malloc() failure, so I'll
do that.  Are we gobbling too much memory again?

I have the ARGUS_MAXFLOW counter to 1M flows, we could
lower that a bit?
