RE: Multi stream UDP test issue
When I run a loop over number of threads sometimes I get up to 4 or 8
threads and than fail and sometimes it fails on single/dual thread
So I guess it may be other issue.
Do u have any command line you want me to check ?
When you refer to multi addresses , all my eth devices are in different
subnets so I don't think this should be issue.

I have noticed that iperf, among other UDP-based applications (such as
nc/nc6), fail when server host has multiple addresses. When the server
has multiple addresses, receives using its address A, but sends back a
response using address B. Now, if A happened to be the default address
of the host, address B usually then equals to A and it actually works.
Otherwise it just fails.
Is this the case also with you? (Probably it is different issue, though)
