    I’m using an ALIX 2D3 (with Battery mod)
    ZS 1.0beta11b
    BA00
    C100
    C110

    Running HTTP Proxy w/ Dan’s guardian.
    1 firewall rule outbound restricting P2P traffic.

    I was running with a consistently low load average (0.00 – 0.07) for months, then last weekend it spiked (0.44 – 0.56).

    The only change I’ve made recently was the addition of the MRTG package and it’s arrival is not consistent with the appearance of the problem.

    Below is the output of the top command:

    top - 12:03:20 up 15:41,  1 user,  load average: 0.64, 0.44, 0.38
    Tasks: 106 total, 1 running, 105 sleeping, 0 stopped, 0 zombie
    Cpu(s): 6.0% user, 8.0% system, 0.0% nice, 85.0% idle, 1.0% IO-wait
    Mem: 255684k total, 239496k used, 16188k free, 12596k buffers
    Swap: 131064k total, 16152k used, 114912k free, 40448k cached

    Below are images from the MRTG package:

    I can only assume that I’m getting high load averages due to memory use (or leak), but I’m not sure why. Has anyone else had this happen? Can anyone help me investigate?

    Thanks much!

    On my opinion the problem is due to the proxy service. Could you disable it or remove the capture rules to see if the system load decreases?

    That certainly frees up memory, but the load is unaffected.

    Hmm.. IO Wait is usually the other thing I look at… Failing disk, but it is at 0.0%

    Perplexing.

    What other things could cause this?

    top - 12:34:03 up 16:12,  1 user,  load average: 0.71, 0.54, 0.46
    Tasks: 68 total, 2 running, 66 sleeping, 0 stopped, 0 zombie
    Cpu(s): 7.4% user, 7.4% system, 0.0% nice, 85.2% idle, 0.0% IO-wait
    Mem: 255684k total, 143692k used, 111992k free, 15024k buffers

    The top command could help you to understand what process is the responsible of the high load average.
