I have two clusters, both configured in active-passive mode using eth8 for ha, on the most recent firmware and no backup interface defined. However, one of the clusters has this error repeating in the logs:
2016:06:03-16:04:12 sophoswp-1 ha_daemon[4235]: id="38A2" severity="error" sys="System" sub="ha" seq="M: 130 12.295" name="send_backup_heartbeat(): send(): Network is down"
In the web interface, everything looks good. Master is Active and Slave is Ready. Physically, the link lights are up and activity lights are blinking. The error was occurring before the last firmware update and persisted after the update. Both nodes updated successfully. Since this is a production system, I am a bit hesitant to just unplug the ha cable until it is confirmed this is an issue and not just a problem with the logging.
