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
