Description (partial)


In J2 platform, when LEM is full, adding new route (IPv4/IPv6/mpls) to LEM takes 0.2 second to fail. This will delay NPU to process other requests. When there are a lot of routes addition requests submitted to NPU threads, system will take a long time to process them. In the meantime, system appears to be unresponsive.

LEM is full and the system continues to add new routes to the LEM may result in this condition
