I have not heard many people suffering from the same problems that you
are. Do the logs record anything useful? (error messages, etc?).

Our main Iperf developer will be returning in August and has been
rewriting Iperf. I'm not sure if this will solve your problems, but you
could wait for that new release (sometime in the fall)  and use your
restart script in the meantime. However, I know that DAST would be very
interested in anymore information you can provide about why you think it
is quiting, and some basic info about your machine (os, etc.). That
information could be helpful during the rewrite.

Thanks,
