Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The external information, such as originating router id, originating protocol, is 0.
Workaround: There is no workaround.
CSCso64607
Symptoms: A router may crash when the no ip vrf command is issued.
Conditions: The symptom occurs when VRF was previously configured on a tunnel interface that
has subsequently been removed.
Workaround: Possibly unconfigure ip vrf before unconfiguring the tunnel interface.
CSCso65193
Symptoms: The memory occupied by the IP SLA Event Processor may gradually increase.
Conditions: The issue occurs when IP SLA jitter operation is configured on the router without
source port specification.
Workaround: There is no workaround.
Further Problem Description: With 1000 IP SLAs configured (200 each of following types:
path-echo, path-jitter, icmp-echo, udp-jitter and udp-echo, each with a unique destination), the
memory allocated for "IP SLAs Event Pr" increases and the level of available processor memory
goes down. This issue will have a performance impact.
CSCso66516
Symptoms: Memory allocated at function "_fib_table_test_cef_table_route_list" function is leaked.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS 12.2(33.02.19)SBK06
and that is configured for CEF-MTR
Workaround: There is no workaround.
CSCso66668
Symptoms: Flexwan line card crashes in Cisco 7600 chassis.
Conditions: Occurs when bre-connect is configured on an ATM PVC.
Workaround: There is no workaround.
CSCso66862
Symptoms: Router crashes due to bus error. The crash is seen after repeatedly removing
virtual-template interfaces under ATM.
Conditions: The crash is seen under the following conditions.
1) Bringing up nearly 3k PPPoE and PPPoEoA sessions. 2) Configuring no interface
virtual-template number under ATM interfaces.
Repeating Step 2 continuously will cause a crash.
Workaround: There is no workaround.
CSCso67141
Symptoms: When a Border Gateway Protocol (BGP) peer is brought down, some of the routes that
were learned may not be removed. If around 200,000 routes are advertised from a neighbor and the
BGP process on the neighbor is then stopped, all routes will be removed the first time. On the second
time, however, around 20,000-80,000 routes may remain.
Conditions: The symptom occurs when the BGP process on the neighbor (that has advertised
200,000 routes or more) is brought down.
Workaround: There is no workaround.
