User raised the issue in the developer forum. See thread at - https://forum.rchain.coop/developer/network-node/out-of-sequence-error-when-running-a-node/#post-19
Chris shared feedback on what is happening and why.
Pawel and Jeremy discussed on Discord 3/15. Decision to continue printing a message so it can be collected in metrics if desired to detect a poor network a node is on.
Please change message to print "INFO main - Out-of-sequence message:" instead of "error"
