That is because you have limited each robot to have up to 4 open
connections at a time (open_conn_lmt = 4). With that limit, you cannot
get 400 req/sec with 100 robots. Moreover, even doing 250 req/sec with
100 robots is very risky -- make sure your transaction queues (plotted
on the autogenerated report) do not grow long, or you will end up with
a best-effort workload!

BTW, mailing list archive contains a few messages explaining the
"virtual memory exceeded in new" error.
