HA Sync sometimes fails and I can't work out why



  • I've got 2 x PFSenses with CARP VIPs between the two one master one backup. The sync seems to work fine and does fail over appropriately etc however on the odd occasion I get xmlrpc sync errors. The sync between the two PFSenses is a cross over cable in a dedicated lan port and they ping each other fine and sync works 99% of the time.

    Below are an excerpt of some logs when it happened. It doesnt seem to be hindering performance, just I don't want any underlying issues to be around!
