Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S2
• CSCee79728
Symptoms: A Cisco 7200 series that operates in the process switching path may crash with a bus
error exception.
Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS
Release 12.2(13b)M2 and that is configured with a serial or POS port adapter. The symptom may
also occur in other releases.
Workaround: Enter the ip route cache command for all interfaces.
• CSCee81490
Symptoms: MALLOCFAIL messages may be generated during an attempt to allocate large negative
and positive memory blocks in the “cpf_process_ipcQ” process:
%SYS-2-MALLOCFAIL: Memory allocation of -1622998781 bytes failed from 0x60B5BE48,
alignment 0
Pool: Processor Free: 371055532 Cause: Not enough free memory
Alternate Pool: None Free: 0 Cause: No Alternate pool
-Process= "cpf_process_ipcQ", ipl= 0, pid= 141
-Traceback= 603DDCB0 603E005C 60B5BE50 60B5C140 60B5C62C 60B59A0C 603D5D1C 603D5D08
%SYS-2-MALLOCFAIL: Memory allocation of 344820739 bytes failed from 0x60B5BE48,
alignment 0
Pool: Processor Free: 363937412 Cause: Memory fragmentation
Alternate Pool: None Free: 0 Cause: No Alternate pool
-Process= "cpf_process_ipcQ", ipl= 0, pid= 141
-Traceback= 603DDCB0 603E005C 60B5BE50 60B5C140 60B5C62C 60B59A0C 603D5D1C 603D5D08
Conditions: This symptom is observed on a Cisco 10000 series that runs Cisco IOS
Release 12.0(24)S5.
• CSCee82681
Symptoms: On an RTR probe, an RSP does not report input or output packets for serial interfaces
of PA-MC-8T1, PA-MC-8E1, and PA-MC-8TE1+ port adapters.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.2(23a)
or Release 12.3 and is more likely to occur when the number of channelized port adapters (such as
the PA-MC-8T1, PA-MC-8E1, and PA-MC-8TE1+ port adapters) that are installed in the router is
high. The symptom may also occur in other releases.
Workaround: Reload the router.
Alternate Workaround: Enter the reload microcode router configuration command.
• CSCee84732
Symptoms: The CPU utilization of a router that is configured for Multiprotocol Label Switching
(MPLS) may temporarily increase to 80 or 90 percent when a peer router is reloaded or when an
interface with a large number of numbered subinterfaces is administratively enabled.
Conditions: The symptom is observed in a rare situation when label distribution protocol (LDP) is
used in configurations with a very large number of numbered interfaces. When this problem occurs,
the output of the show process cpu sorted command shows that the “Tagcon Addr” process
consumes the majority of the CPU cycles.
Workaround: There is no workaround.
• CSCef04163
Symptoms: The subinterface of a link bundle member is not deleted when you reload microcode
onto (or perform an OIR of) the line card on which the channel group is configured.
