Quarry related "show processes memory sorted"

[sukhendra]

Hello,

I have a router and router pid ISR4331/K9

In my router when I enter the command "show proc memory sorted" and the output is below...
ABP_Atcis_GE#show proc memory sorted
Processor Pool Total: 1688360784 Used: 311830448 Free: 1376530336
lsmpi_io Pool Total: 6295128 Used: 6294296 Free: 832

Please help me to understand why "lsmpi_io Pool" free memory is too low. Attached log for your reference.

Hi,

I believe this is normal and you should be more concerned if it was a high value - it seems to be part of the IOS XE architecture. I have the same on my 4000 series -

UK-ABZ-RTR-01#show processes memory
Processor Pool Total: 1695303312 Used: 312811680 Free: 1382491632
lsmpi_io Pool Total: 6295128 Used: 6294296 Free: 832

See below - which may be applicable to IOS XE in genereal.

"Memory Allocation under the lsmpi_io pool

The Linux Shared Memory Punt Interface (LSMPI) memory pool is used in order to transfer packets from the forwarding processor to the route processor. This memory pool is carved at router initialization into preallocated buffers, as opposed to the processor pool, where IOS-XE allocates memory blocks dynamically. On the ASR1K platform, the lsmpi_io pool has little free memory – generally less than 1000 bytes – which is normal. Cisco recommends that you disable monitoring of the LSMPI pool by the network management applications in order to avoid false alarms"

Hi,
Thanks for your feedback. As per your suggestion it is normal and no need to worry.

Thanks.
