iperf (server) termination with "read/write failed"

[Vivek Sawant <vivek --at-- cs.unc.edu>]

Hi Iperfers,

When I run iperf in the (UDP) server mode, it often termianates with an 
error "read failed" or "write failed". This happens after a client 
connected to it has terminated. The experiment involves a series of 
invocations of iperf clients, one at a time, each with different values 
for certain parameters (mostly, different values for -b and -t 
parameters). The client always connects to the same server.

This abnomal termination is a real problem for the automation of this 
experiment. Not being able to count on the iperf server being around 
during the course of a run will make my scripts unduely complicated.

Has this problem seen before? Any idea why this happens and is there a 
workaround or a fix?

Thanks.
