Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S12
Conditions: Removing xconnect on remote PE, resulting in a session(DLCI) FLAP on the local PE.
Trigger is L2TPv3 session flap; this may cause a stale CI->Uidb mapping in internal data-structures
resulting in if-num mismatch in uidb if the old CI is reused by an DLCI on a different interface.
Workaround: Reload the affected line card.
• CSCso04657
Symptoms: SSLVPN service stops accepting any new SSLVPN connections.
Conditions: A device configured for SSLVPN may stop accepting any new SSLVPN connections,
due to a vulnerability in the processing of new TCP connections for SSLVPN services. If “debug ip
tcp transactions” is enabled and this vulnerability is triggered, debug messages with connection
queue limit reached will be observed. This vulnerability is documented in two separate Cisco bug
IDs, both of which are required for a full fix: CSCso04657 and CSCsg00102.
• CSCso15740
Symptoms: The “set metric” clause in the continue route-map sequence is not setting metric
correctly in some particular conditions. This is also applicable in case where the nexthop setting is
done via route-map with a continue clause.
Conditions: The symptom is observed on a Cisco 12000 series router that is running Cisco IOS
Release 12.0(32)SY4. This is platform independent. This symptom occurs if the route-map has a
continue clause and the match condition does not allow the continue clause to be executed. The
following route-map sequence which has to be executed will not execute properly if the metric or
nexthop of the prefix are to be modified via the route-map.
Workaround: Avoid using “continue” in a route-map and modifying metric or nexthop via the
following route-map sequence.
• 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.
• 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.
Workaround: There is no workaround.
• CSCso72996
Symptoms: A SIP601 sometimes crashes or gets an alignment error.
SLOT 4:Mar 17 17:59:03.877 UTC: %ALIGN-3-SPURIOUS: Spurious memory access made at
0x408C1E14 reading 0xF SLOT 4:Mar 17 17:59:03.877 UTC: %ALIGN-3- TRACE: -Traceback=

Conditions: The conditions under which this symptom occurs are unknown.
Workaround: There is no workaround.
• CSCso82147
Symptoms: Line card crashes when packet over SONET (POS) shared port adapter (SPA) is present.
Conditions: Occurs the first time router is reloaded.
