ASR 1K Memory

Hi,

I have a question regarding ASR1K memory. I usually use "show proc mem" to see how much memory is used by the router. Below is the output from my ASR1K

ASR-1K#sh proc mem

Processor Pool Total:  724922940 Used:  258733288 Free:  466189652

lsmpi_io Pool Total:    6295088 Used:    6294116 Free:        972

   5   0      35016          0      17196          0          0 IPC ISSU Dispatc

I have few questions for above output:

1. There are two memory, Processor Pool and lsmpi_io pool, can anyone tell the difference?

2, Why is my lsmpi_io pool memory is used up? I only have 972 byte left. and what can I do to free up the memory?

Another thing is there is a command "show platform software status control-processor brief". Below is the output on my router:

ASR-1K#show platform software status control-processor brief

Load Average

Slot  Status  1-Min  5-Min 15-Min

  RP0 Healthy   0.00   0.09   0.15

ESP0 Healthy   0.00   0.00   0.00

SIP0 Healthy   0.00   0.00   0.00

Memory (kB)

Slot  Status    Total     Used (Pct)     Free (Pct) Committed (Pct)

  RP0 Healthy  1824960  1775944 (97%)    49016 (3%)   1476032 (81%)

ESP0 Healthy  3887632   607448 (16%)  3280184 (84%)   2557700 (66%)

SIP0 Healthy   477712   409444 (86%)    68268 (14%)    339324 (71%)

CPU Utilization

Slot  CPU   User System   Nice   Idle    IRQ   SIRQ IOwait

  RP0    0   1.30   1.20   0.00  97.49   0.00   0.00   0.00

ESP0    0   0.30   0.40   0.00  99.30   0.00   0.00   0.00

SIP0    0   0.50   0.30   0.00  99.10   0.00   0.10   0.00

Few questions for above output:

1. why is the memory usage different (the memory part). with this command it shows that RP0 memory is already used 97%, while using the previous command, the value is different.

2. how can I see which process caused this? because I think I will want to shut that process.

I have read this document (http://www.cisco.com/en/US/products/ps9343/products_tech_note09186a0080af252a.shtml)

, but I still do not understand. It does not explain the output one by one.

Regards,

Prima
