Dashboard leaking memory



  • Leaving the Dashboard page open causes my browser to leak several megabytes per hour.

    I get the same leak with Firefox, and Google Chrome.

    pfsense 2.0 snapshot BETA5 (i386) built on Fri Feb 18 06:31:46 EST 2011

    I have the following Dashboard widgets enabled :

    Services Status
      System Information
      Installed Packages
      Interface Statistics
      Gateways
      Captive Portal Status
      Firewall Logs
      Snort Alerts
      Interfaces
      Traffic Graphs ( at 1s update rate )

    Removing Traffic Graphs looks like it reduces leak rate significantly, though I'm not convinced it prevents it altogether. More testing required.



  • Similar leak rate seen while on Status - > TrafficGraph page

    Those are SVG graphs, so the real problem may be in the browser's SVG function, not just in the page itself.

    Someone who knows more about the inner workings of the SVG graphs may have a more precise answer though.

    Its an outdated product from Adobe…..

    Wonder if newer products exists....

    IIRC, Firefox and Chome support SVG internally and not via an Adobe plugin.



  • Every browser except IE (until v9) has native built in SVG support, likely finding some general issue with SVG leaking memory in those browsers.



  • I'm seeing the same behavior with my pfsense 1.2.3 install.

    At this point I'm inclined to agree that it's a browser issue, but curious that both Firefox and Chrome are similarly afflicted.
