I'm not really seeing a lot in the results you uploaded. Here are a few suggestions to see if we can make some progress.
- Reboot all VMs (including your prime client and client0) and try again.
- If you are still seeing an issue: Although you said you only have one NIC on your primeclient I see two IP addresses. You may want to review your networking configuration. Additionally, it would help if you went ahead and posted your Standby0's /etc/hosts file and it's /usr/local/staf/bin/STAF.cfg file for us to review.
- You could also add the alias "primeclient" to the primeclient's /etc/hosts file (with IP 127.0.0.1)
