Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S
• CSCeg31430
Symptoms: A memory leak may occur on a router that has rate-limiting configured.
Conditions: This symptom is observed when the router is configured with two mutually exclusive
exceed statements as in the following example:
Router#sh run | b <name>
policy-map <name>
class <classname>
bandwidth 50
random-detect
random-detect exponential-weighting-constant 3
random-detect precedence 0 3 9 1
random-detect precedence 7 3 11 1
police cir 50000 bc 8000 pir 119000 be 16000
conform-action transmit
exceed-action transmit
exceed-action set-prec-transmit 0
violate-action drop
queue-limit 22
Workaround: To stop the memory leak, delete one of the exceed statements.
• CSCeg31912
Symptoms: Ingress policing and bandwidth percent per-class do not function and limit traffic at the
configured bandwidth for MLFR links. The output of the show policy-map interface command
shows the configured bandwidth which differs from the actual bandwidth.
Conditions: This symptom is observed on a Cisco 7500 series after the router is reloaded.
Workaround: Remove the service policy and re-apply it to interface to enable correct calculation of
the interface bandwidth.
• CSCeg33229
Symptoms: A VIP may crash when an ingress service policy is removed from an MFR interface.
Conditions: This symptom is observed on a Cisco 7500 series while traffic is being processed on the
MFR interface.
Workaround: There is no workaround.
• CSCeg35517
Symptoms: An Engine 3 1-port OC-12 channelized DS1 line card that is configured for MLP may
reset or may cause the RP to reset.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of Cisco
IOS Release 12.0(31)S.
Workaround: There is no workaround.
• CSCeg37524
Symptoms: A 4-port OC-12 ATM single mode (4OC12/ATM-IR-SC) line card may generate unicast
send timeout errors, %LC-3-PSAERRS errors, and %LC-3-BMAERRS errors, which cause TDP
neighbor flapping and may cause the line card to crash.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(27)S3.
