ASR 1K Error - %PLATFORM-3-ELEMENT_CRITICAL: R0/0: smand: RP/0: Committed Memory value 98% exceeds critical level 95%

Approximately every month the ASR 1K freezes and the traffic stops to pass and some logs appear. Logs below are presenting in console:

Do you have any idea of a workaround for this case ?

The ASR version is 12.2(33)XNE1.


This seems to be this DDTS : CSCtc21042 cman_fp crashes on ASR RP2. Please click here for more information.

Symptom:
Chassis-manager process on RP2 gets stuck and router becomes unresponsive to
user commands. All the FPs and CCs keep rebooting, with console logs showing
repeated FP code downloads.
This problem is specific to RP2.

Conditions:
No particular scenario is known. Problem is caused by OBFL logging of messages
on RP2.
Workaround:
Following workaround greatly reduces the probability of this
issue occurring again, but does not completely eliminate it.

Disable onboard logging of messages on RPs as follows:
"hw-module slot r0/r1 logging onbaord disable"

Router#hw-module slot r0 logging onboard disable

To verify that onboard logging has been disabled:
Router#sh logging onboard slot r0 status
Status: Disabled

Note that this command is not saved in the config so is not preserved
across router reloads.

Please consider the workaround above and also upgrade in future as DDTS not fixed in your OS. It is fixed in 12.2(33)XNF 12.2(33)XNE02 12.2(33)XND03
