Cisco Cisco IOS Software Release 12.4(4)T

CSCeh53673

Symptoms: The router pauses indefinitely during processing the default configurations of l3 cache 
disable.

Conditions: This symptom has been observed when the router loads the image and processes the 
default configuration.

Workaround: Load an working image and configure no cache l3 disable. This command will not 
disable l3 cache. For the command to be effective, reload the router. Boot the effected image as usual 
and this problem will not be seen.

fragmentation as the cause. When this failure occurs, there is approximately 20MB of free memory 
on a gateway with 220MB of processor memory.
