RP/0/RP0/CPU0:Jan 20 15:32:16.918 AST: fib_mgr[181]: %ROUTING-FIB-4-LCL_ATTRIB_ENTER_OOR : FIB has run out of local attribute resources for proto: ipv4, VRF: default,max attribute count: 65536. OOR state: red

Conditions:
This will occur when the number of BGP attributes is >64k.

By default, we only accept 64K BGP attributes when 'bgp attribute-download' is enabled. this gets blown out when accepting a full route table. we have to increase it to 256k.
