Swap in/out throwing an alarm despite having sufficient memory resources. It shows:
This machine is critically short of memory. Start killing unwanted or errant processes.
The message is actually not true and resources are adequate.
You can either turn off the alarm or raise the Thresholds, which can be done by right clicking on the Swap/s flow and selecting 'Metrics...'
Once open, select the Thresholds tab and uncheck the 'Low, Medium and High Severity' if you would like to turn the alarm off or increase the values in the Start and End columns to better reflect the timing of the alarm.
Waiting for fix in a future release of Spotlight on Unix.
