 If a node is oscillating above and below a soft eviction threshold, but not exceeding its associated grace period, the corresponding node would constantly oscillate between `true` and `false`. As a consequence, the scheduler could make poor scheduling decisions.
 
-To protect against this oscillation, use the `eviction-pressure-transition-period` flag to control how long {product-title} must wait before transitioning out of a pressure condition. {product-title} will not set an eviction threshold as being met for the specified pressure condition for the period specified before toggling the condition back to false.
