I am not using SSH connection sharing. Thanks, I'll look into it. I
was running the console in a VirtualBox VM running Fedora 17, hosted
under Windows 7. I did notice that I was getting the same failure if I
ran a grinder test on the Fedora VM and the console together. That
should work as its all done on localhost and there is no SSH
forwarding. Works for 1 test, fails for 5 workers with 5 threads.
I am going to try to run the console on Windows, using SSH forwarding
with Cygwin or PuTTY. I will check out the SSH connection sharing. I
am curious as to why it failed when I ran 1 agent and the console on the
same VM with no forwarding.

I'm pretty sure this will turn out to be a problem with the SSH
forwarding, and not with The Grinder.
Are you using SSH connection sharing? If not, perhaps try enabling it.
If so, try disabling it.
