Issue:
Server availability index is low on systems where memory, processor, and network are all reported as plentiful. (e.g. 1-15% processor peak, 20% network interface(s) peak, and "plentiful" memory).
Availability Index goes down to 0. Users may or may not see access issues. In addition, cluster failover doesn't occur (fails) since both machines are reporting 0 availability index.

Solution:
Adjust the "Server_Transinfo_Range" from the default 6 to something higher (e.g. 8 or 10). Starting in Domino 6.5 and Domino 6.04, the documentation was improved with more information on these settings. See: Database 'Lotus Domino Administrator 7 Help', View 'Contents', Document 'The server availability index' Database 'Lotus Domino Administrator 7 Help', View 'Contents', Document 'Choosing the server availability threshold'.
