CSCvp73396 - Cat9300 Memory Leak due to nyq_rsync.log - 2

[jaros0002]

I have same issue but with IOS  16.12.3a, which is mentioned in "Known fixes releases".... so on which version should i upgrade? 

[Leo Laohoo]

Post the complete output to the following commands: 

sh platform
sh platform software mount switch <SWITCH MEMBERS> r0 | include ^tmpfs.*tmp | exclude /tmp/

I want to see the output of the 2nd command from all switch stack members.

NOTE:  I don't see this bug appearing in 9300 running 16.12.3a.

sh platform software mount switch active r0 | include tmpfs.*tmp
tmpfs 58264 7946812 1% /tmp
tmpfs 8754620 4053504 69% /tmp/rp/tdldb
tmpfs 284 12807840 1% /tmp/fp/tdldb
tmpfs 0 12808124 0% /tmp/cc/tdldb

if i use your command with exclude, it shows just "tmpfs 58284 7946792 1% /tmp"

so is this different case, if i have trouble with "/tmp/rp/tdldb" ? 

i see this in log : %PLATFORM-3-ELEMENT_TMPFS_CRITICAL: Chassis 1 R0/0: smand: 1/RP/0: TMPFS value 55% above critical level 50%

thx for reply im going into production in 1 week so im nervous... 

[Leo Laohoo]

Wait ... I know what this is.
Do you have EPC (enhanced packet capture) enabled?

[jaros0002]

No, i don't. Its brand new switch, i just configure trunk ports, portchannels, radius & tacacs server and some access-list, anything else is default.

[Leo Laohoo]

tmpfs 58264 7946812 1% /tmp

This bug can only be found in this folder.  

Here's another way to determine if you have this bug or not:  Do you have a crashinfo file?  If you do, attach it so I can have a look.

[jaros0002]

It doesnt restart yet, but the usage of this file is increasing about 4-5% per day so... its just matter of time

[Leo Laohoo]

Read THIS.

You need to raise a TAC Case because someone (either you or the TAC engineer) needs to get into shell access.  Only TAC can generate the challenge to get into shell.

[jaros0002]

Sorry man,.. its not 9300 but 9500 -  C9500-48Y4C... does it matter? Should i also  raise a TAC Case? I have more than 60 new swtiches so its confused me... 

[Leo Laohoo]

Yes, it does. This bug does not affect 9500.
I think you need to raise a TAC Case.

I have same issue in 16.12.4.... so, yes indeed, which version to upgrade to?

[Leo Laohoo]

Stay away from 16.12.X. 
Downgrade to either 16.6.X or 16.9.X.

EDIT:

Go HERE and have a look at the troubleshooting method.  Cisco TAC is very adamant this bug is exclusive only to 16.10.X and 16.11.X.  

[Brands2209]

Hi All, Thanks for your help. I upgraded to 17.3.3. Up till now (2 months later) it is holding and doing the trick. Thanks.

[Harrie Hendriks]

We have the same problem with a 9500-40A. We used 17.6.3 

%PLATFORM-3-ELEMENT_TMPFS_WARNING: Switch 1 R0/0: smand: 2/RP/0: TMPFS value 41% above warning level 40%

So looks like updating the switch is not the solution (so far)
