I can't reproduce the problem here.

What version of dkftpbench are you using? What parameters?
Can you send me your kernel .config file?

I did notice and fix an embarassing problem in Poller_bench of
dkftpbench-0.42; it aborted when Poller_sigio sent its initial readiness
notification (it's spurious, but programs are supposed to
be able to handle that). Fix is at
http://www.kegel.com/dkftpbench/pb.patch

Thanks,
Dan
