Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Reduce MTU on tunnel end systems, which increases fragmentation.
Further Problem Description: The problem is reproducible with extended pings of size 1527 bytes,
which get dropped in direction SUP->MWAM as diagnosed with deb ip icmp.
• CSCsb98906
Symptoms: A memory leak may occur in the “BGP Router” process.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(26)S6,
that is configured for BGP, and that has the /jointfilesconvert/422273/bgp regexp deterministic command enabled.
Workaround: Disable the /jointfilesconvert/422273/bgp regexp deterministic command.
• CSCsc78999
Symptoms: An Address Error exception occurs after Uninitialized timer in TPLUS process.
Conditions: This is a platform independent (AAA) issue. It may be seen with a large number of
sessions while accounting is configured with a T+ server.
Workaround: Disable accounting, or use RADIUS accounting instead of a T+ server.
• CSCse29570
Symptoms: Router might unexpectedly reload during CNS configuration download.
Conditions: The downloaded configuration must disable the CNS configuration initial or partial for
this crash to occur.
Workaround: Use static configuration and prevent configuration download from CNS server.
• CSCse87210
Symptoms: On Catalyst 6500 Series and Cisco 7600 Series, when certain service modules transmit
packets to VLANs also used with Distributed EtherChannel (DEC), those packets may be dropped
and lost. For further description, please review “Field Notice: FN-61935 - Catalyst 6500 Series and
7600 Series Service Module Incompatibility With Distributed EtherChannel and Packet
Re-Circulation.”
Conditions: The problem only happens when service cards are operating in crossbar-enabled mode.
Workaround: See the above referenced Field Note for several workarounds.

Conditions: This symptom is observed on a Cisco router that runs Cisco IOS interim Release
12.3(22.13), interim Release 12.4(13.9), or Release 12.4(13b) and that is configured for QoS.
Workaround: There is no workaround.
• CSCsg11616
