Had some network communication issues last night on one of the nodes of a 2
node NW 65 cluster. The node that is abending was the master ip address
resource at the time. The node will continue to abend as long as the master
ip address resource is on the other node. The node will not abend if it is
hosting the master ip address resource.

I get the abend message:

Abend on P00
At least one of the nodes is alive in the old master's node partition. This
node is not in the old master's node partition.

Although the node is running right now it appears to be having intermittent
communication issues with the other cluster node and another standalone NW
server.

It appears both network cards in the problem node are working correctly
now.

Any ideas how to correct this problem?

Thank you,
Monte
