Symptom: When a flat policy is applied to a MLPPP, MFR or GEC aggregation bundle, the current leaf schedule object is replaced with a new one. The code was not updating the cached object which resulted in accessing invalid memory when the bundle bandwidth is updated. The bandwidth is updated when a member link is added to or removed from the bundle. Configuration example: policy-map foo class prec1 bandwidth percent 10 interface Port-channel1 aggregate ip address 126.96.36.199 255.255.255.0 no negotiation auto lacp min-bundle 2 service-policy output foo Conditions: When a bundle schedule is replaced, the cached object was not being updated leading to interface bandwidth update event to access invalid memory. The problem is not easy to recreate as would require the QOS event for processing the flat policy to be interleaved with an interface bandwidth update event.
