CPU spikes on XG115 r3 running as ASG Software license ...

I don't recall seeing these before updating to 9.715-4 ...

(I have also recently upgraded from 4GB to 8GB RAM, but why would that cause anything like this)

They appear spaced evenly every 3 hours, and always start 10 after, so for example 17:10:00 ...

(These are not traffic related, normally I've seen this box average 2% over the span of a few days)

  • The weekly graph illustrates how this issue started a few days ago ...

    I have also confirmed the issue was not cause by memory upgrade, as the upgrade happened before the spikes started as seen by the memory usage drop form 50% to 25% ...

  • Hi  ,

    mdw.plx is the middleware taking 99% of CPU 

    Check the following in the shell: 
    1.) ls -lah /var/storage/cores
    2.) tail -f /var/log/mdw-debug.log
    3.) tail -f /var/log/confd.log
    4.) also you can try restating that service: /etc/init.d/mdw restart

    And additionally check your DNS settings, this could lead to due misconfiguration as well. Also try fine tuning the rules and groups.

    Thanks & Regards,

  • Thank you for your troubleshooting notes, here's what I have noticed:

    1) There is nothing in /var/storage/cores ...

    2) I captured /var/log/mdw-debug.log just before and during the spike ... see below

    3) Also captured /var/log/confd.log just before and during the spike ... see below

    4) A restart of mdw didn't help.

    There's nothing incorrect with my DNS, just one availability group with 2 DNS servers, no request routing, etc.

    There has been no configuration changes done recently,- around the time this has started, so I do not think it's due to configuration.

    /var/log/confd.log

  • Logs look normal, nothing suspicious I can point to. 
    Have you tried rebooting once ?

  • Whatever it was, it now seems to be resolved ...

    I have rebooted, and did a touch /forcefsck as well as cleared log files and also did a postgresql rebuild.

    Thank you for your time!
