Multicast routing is unable to acquire memory for a flow. Router memory is oversubscribed. Reduce the number of VLANs or the number of features in use. Remedies include one or more of the following:

• Reduce the number of configured VLANs by moving some VLANs to another router.
• Free up system resources by disabling another feature, such as one of the spanning-tree protocols or either the RIP or the OSPF routing protocol. (Unless you are using static routes, you will need to retain a minimum of one unicast routing protocol.) Another option that may help is to reduce the number of configured QoS filters.
• Move some hosts that create multicast demand to another router.
