Hi Yong Hao,
Thanks for your reply,
1), The Jgroup config is reside in the cluster-service.xml ? I have zipped in the attachment, and I don't figure why the timeout is 2 minutes.
2), There are several places (postoffice control channel/ postoffice data channel, Jgroup, others? ), which one will be the checkpoint of timeout to drop node from clustering ?
Thanks again!
