It suggests that netserver died - I would check for netserver core files 
and then see what their backtrace shows.

That, and/or make sure you are using the latest bits from the 
repository.  The headers in your netperf client output, and some of your 
prompts suggest your netperf version is rather old.  There have been 
fixes related to netservers dumping core during UDP tests.
