RUT241 / RUT2M_R_00.07.09 snmp causing high CPU load

After installing RUT2M_R_00.07.09 on our RUT241, I started getting timeouts when pulling SNMP statistics. After inspection, it turned out that the snmpd daemon was causing issues - creating 100% CPU load. Disabling snmpd solved the issue. I’ve rolled back to RUT2M_R_00.07.08.2 on our RUT241

On our RUTX50 and TRB140 devices, I do not see the same issue.

Hello,

Could you please clarify whether you are performing a full SNMP walk or simply requesting individual SNMP objects? Additionally, is there any pattern in the specific SNMP objects being requested? Understanding this might help us pinpoint whether the issue is related to a particular set of requests or if it occurs under specific conditions.

Best regards,

Hi,

I’m sorry for not getting back to you sooner. I’m using SNMP exporter from prometheus. It walks the following oid’s every 20 seconds with a 20s timeout:

This is a snippet from the snmp.yml config file for SNMP-exporter.

    walk:
    - 1.3.6.1.2.1.2
    - 1.3.6.1.2.1.25.1
    - 1.3.6.1.2.1.25.2
    - 1.3.6.1.2.1.31.1.1
    - 1.3.6.1.4.1.2021.10
    - 1.3.6.1.4.1.2021.11
    - 1.3.6.1.4.1.2021.4
    - 1.3.6.1.4.1.48690.1
    - 1.3.6.1.4.1.48690.10
    - 1.3.6.1.4.1.48690.11
    - 1.3.6.1.4.1.48690.2
    - 1.3.6.1.4.1.48690.3
    - 1.3.6.1.4.1.48690.4
    - 1.3.6.1.4.1.48690.5
    - 1.3.6.1.4.1.48690.8
    - 1.3.6.1.4.1.48690.9

I’m also pulling data from a RUTX50 running RUTX_R_00.07.09.1 and a = TRB140 running TRB1_R_00.07.09.1 without any problems.

Hello, we are seeing the same thing with a RUT360 running RUT36X_R_00.07.14.2.

We are walking the following MIBs (our snippet from snmp.yml config file for SNMP-exporter)

    walk:
      - 1.3.6.1.2.1.1
      - 1.3.6.1.2.1.2
      - 1.3.6.1.2.1.31.1.1
      - 1.3.6.1.4.1.48690.1
      - 1.3.6.1.4.1.48690.10
      - 1.3.6.1.4.1.48690.2
      - 1.3.6.1.4.1.48690.4
      - 1.3.6.1.4.1.48690.5
      - 1.3.6.1.4.1.48690.6
      - 1.3.6.1.4.1.48690.7
      - 1.3.6.1.4.1.48690.8
      - 1.3.6.1.4.1.48690.9

Any help or insight would be appreciated!

Hello @plotlogic-aj,

Could you please let me know which firmware version is currently installed on your device?

Best regards,

Hi @Marija, we are running:

  • Firmware version: RUT36X_R_00.07.14.2
  • Firmware build date: 2025-05-07 11:17:29
    Thanks!

Could you please check if the same issue occurs with firmware version 7.14.3?
You can download it from the following link: RUT360 Firmware Downloads - Teltonika Networks Wiki

Additionally, when updating to version 7.14, please make sure you followed the instructions outlined here: Important Note About Firmware Update

If you haven’t followed them, during the firmware update process, make sure to untick the “Keep settings” option.

Let me know how it goes!

Best regards,

Hi Marija,

I have upgraded our test RUT360 to 7.14.3. We still see the same behaviour - see screenshot below. In this test, we’ve configured our SNMP exporter to walk the SNMP MiBs listed in my previous post every 20sec. You can see where I started the SNMP test, in the middle of this graph.

Hello,

I’ve sent you a form to fill out. Once it’s completed, I will contact you privately regarding this issue. Please use the ticket ID "7723-2" when submitting the form.

Best regards,

Hi @Marija, if your last message was directed at me, I haven’t received any form. I’m not sure by which “private” method you are going to use to contact me.

Cheers!
