[Xymon] Peer not up, flushing message queue

After recently migrating from virtual server to physical (xymon 4.3.10), I'm seeing the rrd-data.log and rrd-status.log filling up with the error "Peer not up, flushing message queue". and many "Trends" graphs with "NAN' values. Don't know how to fix this.
