I am using domino server v9.0.1 FP5 on windows 2012 Hyper-V.
I am experiencing zero availability index very often during the day and during that instant the user experience very slow response from the server and their clients hangs.
I have monitored following things during the instant of zero availability
1- Disk I/O-----> Disk I/O is not showing any abnormal hikes
2- Network Response-------> During the event I pinged the server continuously during the event and network response is 1ms to 10ms
3- Domino Server Tasks-------> During the event the Indexer task was consuming around 9% processing and all other tasks were mostly IDLE or using low resources
4- Memory Consumption for both domino server tasks and over all OS----> It was also not at all alarming
