[garner] konstant 30% CPU, resolve Cache error

Hi there,
Sophos XG230 and v19.01.
We have here permanently 30% CPU from garner process.
Looking closer with "tail" you can see the following.

usercache_output: resolve_gr_cache for FW_PBR_MODULE failed
usercache_output: resolve_gr_cache for FW_PBR_MODULE failed

I think that is not correct.
How to get this problem solved ?

thx

  • Hello  ,

    Thank you for reaching out to the community, On the CLI, select option 5. Device Management, then option 3. Advanced Shell.  
    type the command: service garner:restart -ds nosync

    And then check the logs again !!

    Thanks & Regards,

  • How many route base tunnels are configured ?

    Then Since when did you notice this logs generating?

    As garner service is responsible for the logging and reporting part, have you faced any problems in generating reports from the reports dashboard or missing logs from the log viewer section ?

    Thanks & Regards,

  • >How many route base tunnels are configured ?
    only two, but with more routes and larger subnets.

    >Then Since when did you notice this logs generating?
    After switching to v19.01, i noticed that on average, when the users are in the company, we have 50-60% CPU load.
    That was about 15- 20% less before.
    What is also noticeable in this context is that snort and garner are the main causes of the high CPU load.

  • Snort is responsible for IPS.
    During this increase in CPU load, have you faced such troubles like:
    1.) Access to the web GUI FW ?
    2.) ssh access ?
    3.) Number of users ? - Do you they face any troubles accessing the internet or any slowness ?
    4.) Network impact - LAN/WAN ?

    Thanks & Regards,

    i know :)
    Regarding points 1,2 and 4.
    No problems at all, except this garner and snort CPU problem.

    To point 3.
    120 users, currently about 20 in HO (home office).

    That should not be a problem for the XG230.
    What i read / see, however, that there are always complaints with garner / snort in terms of high CPU utilization.
    This is already an older problem.

  • Is there at least a chance to solve the garner / cache problem ?

  • Can you share the out of the: less garner.log | grep threshold

    >  Screenshot of the system services > log settings 

    Thanks & Regards,

  • Hey   also the output of - less garner.log | grep threshold 
    Are you using all the modules/services and do you require logging of each and every option ticked ?

    Thanks & Regards,

    >Are you using all the modules/services and do you require logging of each and every option ticked ?
    True, some could be deactivated, but most are transferred to a central Elasticsearch cluster for log analysis.

  • So there are no drop events, as it has not exceeded the threshold. 
    Yes, I would request you to untick the options which are not required at least on the local reporting side !!

    Thanks & Regards,
