Hi Russell,
    This looks like the same problem we saw on 29-Mar ( 51998 ).  I
filed a PR ( #2218 ) that night.  Robert suspended it later when he
could not reproduce the problem.  I have reassigned it to him now
that the problem has re-surfaced.  If he has trouble reproducing it
today, maybe you and he can get together and get it sorted?   It
seems that any TRACK command from the TCC causes the failure.
				Cheers,
