BGP import policies with match action drop (or md-cli reject) and bgp-leak, can cause memory utilization to increase whenever a route matches the policy entry's criteria. Any changes to policy, or removing, re-adding an import policy with such an entry, which matches a route or set of routes will also cause memory utilization to increase. In some cases where there are a lot of routes and/ or lot of changes, the memory utilization may increase to a point where the CPM runs out of memory and cause system wide instability.
In a redundant system, a dual CPM SWO can help clear the memory utilization, but the same set of actions will start increasing utilization again. [453453-MI]
