No physical address for x, dropping message on node restart in jgroups cluster

My node log is flooded with warn message of "Dropping unicast message to wrong destination" when one of the node in the cluster is restarted . we are using Jgroups, TCP, version of jgroups-3.4.1.Final. My server does not come up , with these warning messages contagiously thrown up

Below are the warning messages [0;33mWARN [TransferQueueBundler,h-broadcast,h-13] [TCP] JGRP000032: h-13: no physical address for 8281f201-7fb1-f6ac-faf3-d6837bc39087, dropping message

[0;33mWARN [INT-1,h-broadcast,h-13] [TCP] JGRP000031: h-13: dropping unicast message to wrong destination d205fcba-151c-ad58-8323-fe4f49117f88

Please let me know how to resolve for this issue

Thanks, Nivedita

Solution

  • Thanks a lot for the suggestions. The cluster nodes self healed itself, when one of the problematic node was made down ( it was unable to telnet in comparison to other nodes which were able to telnet)
