9.352-6 Memory leak

IanMorehouse

My home system memory use uptil October 2015 used to sit around 25-30% of 8gb. Today it is stting around 54% and growing.

Yes, if I restart the UTM the memory use will return to the base level and then start growing again.

Another UTM I manage started generating the daily reports with graphs about 2 days after the upgrade and its memory use is slowly incrementing, currently around 40% from a base of about 20%.

  • Those percentages don't seem too bad, but it also depends how much traffic is passing through as well. You've now established a baseline and can monitor over time how much they rise. Using the shell tools I mentioned, you can also see specific amounts of RAM used. Another good tool for spotting leaks are the memory usage charts at Logging & Reporting > Hardware. If there's a leak, you may see a steady uphill climb.

    Have you ever tuned IPS? This involves disabling rule sets that are not applicable to your environment and turning off older rules.

    IPS has been tuned, might need a minor review with some of the newer rules. At the time I took that stats view there was very little traffic going through the UTM. I also notice the the base cpu is rising. We are talking from 2.5% to 5%.
    CSSD is running 4.3%

    IPS tuning - currently running 1146 rules out of 25082.

    An update was installed (IPS or anti-virus) yesterday that caused memory useage to drop by 17%. The utm has not been restarted for 17 days.
