Hi,

Please let us know the make,model and IOS version on the device.

check in the fie system if there is any old or retired files.

 

my model is: C1941K9 IOS version: 15.2(4)M6a.

to know which all uses your memory you can use the below commands

R2#sh processes memory ?
  <1-2147483647>  [pid]
  init            Display memory allocated for *Init*
  mlite           Display memory allocated for *MallocLite*
  sched           Display memory allocated for *Sched*
  sorted          Show sorted output based on memory used by process
  |               Output modifiers

Hey,

what i think of memory would be,By default, RAM is broken up into two main areas - Main Processor Memory, and Shared I/O Memory. Main Processor Memory is where the routing table, ARP tables, and running configuration are stored. Shared I/O Memory is used as a buffer location for temporarily storing packets prior to processing. ​
