Resolved Caveats—Cisco IOS Release 12.0(27)S2
• CSCed46184
Symptoms: VPN sessions may not be established.
Conditions: This symptom is observed in an Xconnect configuration when a CFI interface goes
down after the VPN service is being established. This is a timing issue.
Workaround: Remove and reconfigure Xconnect.
• CSCed46669
Symptoms: On a Cisco 12000 series in a dual-RP (GRPs or PRPs) SSO mode, when certain
configuration commands are typed such as a nested policy-map command, the standby RP may
crash. While the RP reboots after the crash, it is not available to perform its standby function.
Conditions: This symptom is observed in Cisco IOS Release 12.0(22)S or a later release. A nested
policy-map command can cause this problem. In general, any configuration command that uses a
large amount of processor stack space, such as the nested policy-map command may, may cause the
standby RP to crash.
Workaround: There is no workaround.
• CSCed46747
Symptoms: After an SSO and before a standby RP is completely up, when you perform and OIR of
line cards, a configuration synchronization failure may occur and the standby RP may reload
unexpectedly.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S when you perform an OIR of an 8-port Packet-over-SONET OC-3c/STM-1 single
mode line card and a 4-port ISE Packet-over-SONET OC-12c/STM-4 single mode/IR SC connector
line card.
Workaround: Perform an OIR of these line cards after the standby RP is up.
• CSCed48941
Symptoms: A Cisco MGX 8800 series Route Processor Module XF (RPM-XF) may crash and
generate the following error message:
No memory for XCM tempbuffer logged
Conditions: This symptom is observed on an RPM-XF that functions as a provider edge (PE) router
in a Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) when you enter the
clear interface sw1 command multiple times on the RPM-XF.
Workaround: There is no workaround. The fix for this caveat is also integrated in images that support
the Cisco 10000 series, such as Cisco IOS Release 12.0 S.
• CSCed49303
Symptoms: A Cisco 12000 series that runs 12.0(25)S2 may report the following log message:
SLOT 1: %SYS-3-CPUHOG: Task ran for 2052 msec (1/1), process = CEF LC IPC Background,
PC = 400DC728.
-Traceback= 400DC730 40DBFE60 40DBFFD4 40DC0B14 400C5A04 400C59F0
Conditions: This symptom is observed when the default route gets updated to Engine 3 line cards
and is reported by these line cards as seen above. This situation may happen after an interface flap
or a routing update elsewhere in the network.
To determine if your line card is an Engine 3 line card, enter the show diag slot-number EXEC
command, in which the slot-number argument is the slot number that reports the message). In the
command output, you will see “L3 Engine: 3” for Engine 3 line cards.
Workaround: There is no workaround.
