Wafl memory utilization keeps fluctuating
Applies to
- FAS arrays over FCP
- ONTAP 9.4 and later version
Issue
- Multiple EMS events can be seen over time where wafl memory utilization fluctuates and availability varies from 1 GB to 3 GB
wafl.memory.statusLowMemory
wafl.memory.statusVeryLowMemory
- Performing TO/GB clears the thread and events were not seen for few days but fix is to upgrade the ONTAP to the fixed version
