Hi,
I have a cluster setup with two nodes on different machines. The setup has been working fine from the begging but lately I face the following problem. I have a process running on the cluster every morning that keeps the servers busy for some minutes(10 min). I noticed that not always but every now and then one of the nodes is suspected and shunned from the cluster but it never rejoins the group even when I restart the node. It seems that at the begging of the problem node 2 does not leave the group saying that it waits for an exit message and then it says that it is the coord and is being suspected???
The log file of node 1 (192.168.202.56) is:
