Resolved Caveats—Cisco IOS Release 12.0(33)S2
Workaround: Avoid using “continue” in a route-map and modifying metric or nexthop via the
following route-map sequence.
• CSCso32397
Symptoms: An unexpected reboot occurs because of a software-forced crash.
Conditions: This symptom is observed when changes are made in the policy map.
Workaround: There is no workaround.
• CSCso41824
Symptoms: A router crashes with an unexpected exception to CPUvector 300.
Conditions: This symptom is observed when you configure MPLS trunks on an 4xT3E3 SPA with
FR IETF encapsulation.
Workaround: There is no workaround.
• CSCso46427
Symptoms: A device may crash when the show clns interface command is issued on the wrong
interface.
Conditions: The symptom is observed when there are a number (around 100 or more) CLNS
interfaces on the device.
Workaround: There is no workaround.
• CSCso51637
Symptoms: Router crashes.
Conditions: Router may crash in some cases after removing interface Auto-template and
unconfiguring auto-mesh with large number of active mesh auto-tunnels. Currently, this crash has
only been observed occasionally with internal scale test scripts and has not occurred with manual
configuration.
Workaround: Wait until all auto-tunnels are down after unconfiguring auto-tunnel mesh globally,
and before removing interface Auto-template
• CSCso54167
Symptoms: BGP peers are stuck with table versions of 0. BGP peers do not announce any routes to
neighbors.
Conditions: Whenever the interfaces flap with online insertion and removal (OIR) multiple times,
all of the BGP peers using such interfaces for peering connections encounter this issue.
Workaround: Delete and reconfigure the neighbor.
• CSCso64050
Symptoms: Policy-map outputs are not seen in standby router. The policy is attached to the VC in
the standby, but no output is seen.
Conditions: The symptom is observed when an ATM PVC is created and a service policy is attached
to the PVC.
Workaround: There is no workaround.
• CSCso65266
Symptoms: A customer upgraded to Cisco IOS Release 12.0(32)Sy4, and now the customer is seeing
a memory leak in the BGP process. The memory leak is happening with the BGP router process at
the rcache chunk memory when the route map has a “continue” clause in the configuration.
Conditions: The leak is seen when a “continue” statement is configured in an outbound route map.
