Running Oracle 10gR2, 10.2.0.4 CRS/RAC on OpenVMS.
Soon after having added a 3rd node to the existing 2 node CRS/RAC cluster, instances have been evicted two separate times.
The first eviction was on node <node2> and occurred at 01:10 in the morning on 18-SEP. <node2> is one of the original two nodes.
The second crash was on node <node1> and occurred at 01:33 on 20-SEP. <node1> is one of the original two nodes.
At that time of the two evictions, the cluster nodes were very busy.
Added a third node to the existing 2 node CRS/RAC cluster.
This change altered the CPU and I/O loading across the cluster.
