You might have some network issues as these messages are from connectivity issues trying to sync to the destination. Check the console screen, go to CTRL + ALT + N then check the NICs and go to "Info" for each NIC to see if there are any dropped packets and check for the seed "1000" and make sure it is "Full duplex".

Link below provides details of the messages.
