This release requires UIM 8.40 or higher. These fixes will be included in UIM 8.5.

memory_usage_exceeded_threshold = 1
6. Reboot the machine when possible and check to see if the alarm_enrichment probe activates with no issue.
7. If the problem is not resolved, change the settings in the nas,cfg recommended in step #5 to the following instead:
lower_memory_usage_threshold_percentage = 0.80
upper_memory_usage_threshold_percentage = 0.80
memory_usage_exceeded_threshold = 3
