Resolved Caveats—Cisco IOS Release 12.0(29)S
• CSCee76167
Symptoms: Several spurious memory accesses occur with ATM PVCs, and an error message and
traceback similar to the following one may be generated:
%ALIGN-3-SPURIOUS: Spurious memory access made at 0x601B5190 reading 0x74
%ALIGN-3-TRACE: -Traceback= 601B5190 601B7B20 601B69D4 60176F64 6017776C 6017755C
6055508C 60555EA0
Conditions: This symptom is observed when you create ATM PVCs or when you enter the clear
interface atm or show atm vc command.
Workaround: There is no workaround.
• CSCee76306
Symptoms: A Cisco router crashes during a period of high routing protocol activity.
Conditions: This symptom is observed on a Cisco 10720 that runs Cisco IOS Release 12.0(21)SP or
a later release or Release 12.0(22)S or a later release.
The crash is most likely to occur when the router holds a large number of IPv4 prefixes in its routing
table and when there is a lot of turnover in the routing table, that is, prefixes are added and deleted
on a rapid basis.
Workaround: There is no workaround.
• CSCee77328
Symptoms: The PXF forwarding engine on a Cisco 10720 may crash after the microcode is reloaded
either through a manual reload by entering the microcode reload pxf command or after a previous
PXF crash. This situation causes multiple PXF crashes.
Conditions: This symptom is observed on a Cisco 10720 that runs Cisco IOS Release 12.0(26)S or
a later 12.0 S release, all of which contain IPv6 PXF packet forwarding functionality, and is most
likely to occur while IPv6 packets are passing through the router.
Workaround: Disable IPv6 functionality or disable PXF by entering the no service pxf command.
• CSCee95978
Symptoms: A Cisco 7200 series with an NPE-G1 may crash when you ping 50 5200-byte packets
from one router that functions as a generator via the Cisco 7200 series with the NPE-G1 to another
router that functions as a reflector. The three routers are connected back-to-back via static routers.
Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS Release 12.3(9a)
but may also occur in other releases.
Workaround: There is no workaround.
• CSCee96231
Symptoms: A Channel Interface Processor (CIP2) and an xCPA port adapter fail to load their
microcode. The microcode bundle is expanding such that the files do not have the prefix. For
example, the file cip28-17_kernel_hw4 is _kernel_hw4.
Conditions: This symptom is observed on a Cisco 7200 series and a Cisco 7500 series. A list of the
affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCee13801. Cisco IOS
software releases not listed in the “First Fixed-in Version” field at this location are not affected.
Workaround: There is no workaround.
