PROBLEM: (94522) (PATCH ID: TCR540-016)
********
Cluster alias connections may not be distributed to the configured cluster
members according to the selection weights defined for the cluster alias.


PROBLEM: (94116) (PATCH ID: TCR540-017)

This patch fixes a memory leak in the cluster alias subsystem.


PROBLEM: (BCGMP23CZ) (PATCH ID: TCR540-034)
********
Numerous nodes in a clusters can go down with "Kernel
Memory Faults" when a security scan (nessus) is run 
against the cluster.
