[httperf] A strange output

I got the following weird output on an httperf run I did:

It's completely mystifying what might have produced this output - is it 
a problem on the target server, a problem on the host running httperf, 
or both?

What seems strange to me about it is that it appears that httperf 
doesn't retry the connections which were "connreset" here (my until now 
experience with httperf has been that reset connections were retried and 
resulted in either a successful sessions or in some other type of error).

But here all the errors are connreset - could someone please enlighten 
me as to what might be going on?

Thanks in advance,
- John
