Memory Usage



  • Hello Everyone,

    Memory usage: 85% of 993 MB

    When i go check my PfSense this morning, I saw the memory usage at 85%.What could be the cause for that ? That something I can do for drop this ?

    Thanks All,



  • That something I can do for drop this ?

    Uninstall some packages that are chewing up your memory?  My 2.2.4 is at 11% of 2GB, and I have squid, squidGuard, Sarg & Lightsquid running.

    That my System Activity whcih should I uninstall ?



  • Showing me a list of system processes isn't that helpful.

    Which version of pfSense, and i386 or x64?
    What packages, if any, do you have installed? (System - Packages - Installed Packages)
    If you reboot the unit, does it come back up at 85% or does it crawl upwards over time?
    What does Status - RRD Graphs - System - Memory show?  Is the memory usage flat or does it climb over time?



  • Version : x64
    Package Install : pfBlocker - squid3-dev - squidGuard-devel
    When i restart the same thing happen.

    Yeah, either remove the Squid* stuff or get some decent RAM.

    426M   417M kqread  1 121:16  0.00% (squid-1) -f /usr/pbi/squid-i386/etc/squid/
    ```  <- squid proxy is using 417 mbyte allready


  • Thanks Guys,

    i will remove it and i will check if it will drop my memory usage.



  • By default, squid only uses 8MB or something.  And like I said earlier, I'm running squid3 and squidGuard, and only using 11% of 2GB.  Magny, what do you have for Services - Proxy Server - Local Cache - Squid Memory Cache Settings - Memory cache size?



  • Memory cache size
    8

    This is the amount of physical RAM (in megabytes) to be used for negative cache and in-transit objects. This value should not exceed more than 50% of the installed RAM. The minimum value is 1MB.
    Maximum object size in RAM
    32

    @KOM:

    By default, squid only uses 8MB or something.

  • Yes, I know but users usually tune this particular option so it's what I check first.  It still shouldn't be a problem if he has used the default 16x256 cache structure.
