*Init* and *IP input* process high memory usage

[Greg Maaaag]

Good day!

We've got Cisco 881 and some why process *Init* uses most memory:

HI,

 Anyone can tell me that what *init* process will do in cisco routers? 

[Moath Hassonih]

Init is a fixed value, that allocates memory when the router is booting and also reserve some memory if necessary for certain configurations/feature, this is a fix value and will not increase over the time . When the IOS boots, the system_init function runs which initializes all of the data structures, devices, configuration, etc . The amount of space taken by INIT depends on the configuration on the router.
