Message Meaning
Unable to alloc a msg buffer for
< text-message > (<counter>)
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.
