CLUSTER_CREDITS

   CLUSTER_CREDITS specifies the number of per-connection buffers a
   node allocates to receiving VMS$VAXcluster communications.

   If the SHOW CLUSTER command displays a high number of credit
   waits for the VMS$VAXcluster connection, you might consider
   increasing the value of CLUSTER_CREDITS on the other node.
   However, in large cluster configurations, setting this value
   unnecessarily high consumes a large quantity of nonpaged pool.
   Each receive buffer is at least SCSMAXMSG bytes in size but might
   be substantially larger depending on the underlying transport.

   It is not required for all nodes in the cluster to have the same
   value for CLUSTER_CREDITS.

   The default value is currently 32. Unless a system has very
   constrained memory available, VSI recommends that these values
   not be increased.
