• CSCee53667
Symptoms: A ping to an interface of an Engine 3 Gigabit Ethernet line card fails after an RP
switchover occurs.
Conditions: This symptom is observed on a Cisco 12000 series that functions in SSO HA mode when
an RP switchover occurs after the line card has been reloaded.
Workaround: There is no workaround.
• CSCee67278
Symptoms: A VIP may crash with a bus error and generate the following error message:
%ALIGN-1-FATAL: Illegal access to a low address
This occurs after the following scheduler error in the “req_proc” process:
%SYS-2-INTSCHED: ’sleep for’ at level 2 -
Process= "req_proc", ipl= 2, pid= 27
Conditions: This symptom is observed on a Cisco 7500 series that runs a Cisco IOS image that
contains the fix for CSCec07487 when a PA-MC-8TE1+ is installed in the VIP.
Workaround: There is no workaround.
• CSCee67746
Symptoms: An E4+ POS line card reports %TX192-3-PAM_MODULE and %TX192-3-PAM_PIM
errors. On rare occasions the line card may crash when it receives a malformed packet.

occurs.
Workaround: There is no workaround.
• CSCee71156
Symptoms: Unexpected behavior may occur when the tx-ring-limit ring-limit command and HQF
are configured: a memory leak may occur in the pool manager of the router.
Conditions: This symptom is observed when traffic is sent at high speed (higher than the line rate)
and when the ring-limit argument is less than 255.
Workaround: There is no workaround.
• CSCee72906
Symptoms: A VIP may crash when you remove a service policy from a multilink interface or when
a member link is removed from the multilink interface while heavy traffic is being processed.
Conditions: This symptom is observed on a Cisco 7500 series that has an RSP and that is configured
for dLFI over a leased line, MLP, and QoS.
Workaround: There is no workaround.
