%PLATFORM-3-ELEMENT_CRITICAL: R0/0: smand:  SIP/0: Committed Memory value 109% exceeds critical level 100%

Dear Amos

Thank you.

This is a legitimate software bug in IOS and it is a known defect CSCto03123. While this is a very old bug and so, there are many a release that has the fix, Cisco’s suggestion (as of today) is to go to  asr1000rp2-advipservicesk9.03.16.04b.S.155-3.S4b-ext


The main symptom of this defect is that cm_heartbeat messages are not freed from memory when the system no longer needs them (i.e. a memory leak). The following line of the output you sent shows that there are approximately 860K of these messages currently leaked:
[cm_oir] message cm_heartbeat/701714127c8fe4259d164ce22ed416bd/0 created:867811 destroyed:0 diff:867811

The leak is slow enough that it typically does not become an issue until the router has been up for 2-4 years.

Looking at the output below, you can see that while SIP0 is in critical state, SIP1 is also showing excessive utilization (85%)


Memory (kB)
 Slot  Status    Total     Used (Pct)     Free (Pct) Committed (Pct)
.
.
.
 SIP0 Critical   449776   444524 (99%)     5252 ( 1%)    487996 (108%)
 SIP1 Healthy   449776   444552 (99%)     5224 ( 1%)    381388 (85%)



Please take the findings to your team and discuss further.

Kind regards … Palani

Hello,

you could be hitting this bug:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCtj47922/?referring_site=bugquickviewredir

The issue is purely cosmetic and has no performance impact.

The bug (CSCtj47922) cited is *resolved* in the IOS Amos stated. So, it is not correct to move on, tagging as cosmetic. Having said that, I see where the confusion came from. The "known affected" and "known fixed" show 15.1(2)S. It is kinda hard to explain this. Working on cleaning the bug contents. Once done, I will reach out, seek feedback and take them back.

Generally speaking, if you see warnings relating to committed memory, then it calls for further investigation.

Amos - kindly consider uploading the show tech. We need to review its contents, to see what we can find.

Kind regards ... Palani

Hi Palani,

I issued the "show tech" command but the output shows my entire config in detail and is too long an output for me to edit out confidentials. is there a more specific command I could use in order for you to assist other than this one?

Thanks.

Hi Amos

Ok, I understand. See if you can send the output from:

  • term len 0
  • term exec prompt timestamp
  • show ver
  • show inv
  • show log
  • show platform
  • show platform software process list 0 sort mem
  • show platform software status control-processor brief
  • show platform software memory messaging chassis-manager 0

The contents of https://www.packet6.com/saving-your-putty-sessions-to-a-log-file/ may help with logging the CLI output to a file, rather than rely on terminal buffer.

Sincerely ... Palani

Hi Palani,

I have attached the command outputs. please have a look,

thanks.

When you get a chance, kindly take a look at

and see what is visible is helpful.

If you would like to see additional info, please let me know.

Sincerely ... Palani

Palani,

thanks for the link ! Looks like the affected and fixed versions have been changed, it was indeed confusing to see 15.1(2)S listed in both.
