Virt-V2V failing with Didn't receive full volume message

I am evaluating RHEV 3.0 for installation at my organization.   Unfortunately I am having issues converting VMs from VMware to RHEV.   The conversion begins and files are written to the export domain, but them the message "Didn't receive full volume. Received 7085617704 of 12884901888 bytes" appears on the screen and the virt-v2v process removes the files it started to write to the export domain.   I have a case with Red Hat on this, but was wondering if anyone else has seen this.

Thanks.
