If this is a machine without much randomness (eg you don't use the keyboard or
mouse, because this is probably some data collection device at a remote site,
right), then maybe that is the problem. Can you try the same configuration on
a fast link? That would help identify the problem.
One solution might be to get a newer machine that has build in random
generator, or change the sources of entropy.
