[httperf] Ideas on error "Address already in use"?

I'm trying to check my test environment and see if everything is ok.
For that, I try making requests to a server I know will support the stress

Does anybody know what could be the possible reasons for httperf to
get a ERRNO 98 (Address already in use)
when doing the tests? Or how could I find what's happening?
(I'm testing using ulimit -n 65535)

Thanks in advance!
