Possible bug in loadbalancer?

Hi,

Trolling though the log files I found several errors which were all of the
following form.
I believe I have been using ELB correctly, but anything is possible and I do
not yet
have much experience with it. This version is from the git repo which I
cloned last
Friday.

I doubt that I can do much to reproduce this error, so if this trace helps,
that's great.
I will keep an eye out for other misbehavior as well.

Thanks for the great work you guys have put into starcluster and the elb.

Regards,
