URL constantly hitting site, killing RAM

  • My site is going down for 30 minute +/- a day, at varying times, because the RAM is being overloaded. After doing some digging into the problem tonight I believe it has to do with Wordfence and Ajax.

    When I look at recent visitors to the site through my hosting, this shows up in the record constantly:

    IP: 74.125.44.78
    URL: /wp-admin/admin-ajax.php
    TIME: 3/9/15 9:23 PM
    SIZE (bytes): 142
    REFERRING URL: https://www.enduringepilepsy.com/wp-admin/admin.php?page=WordfenceSecOpt

    It visits the site sometimes 3 or 4 times a minute and I have no idea why???

    I’ve shut off Live Traffic. But this appears to be security.

    I don’t know what it is – A setting? A line of code? – but I need to fix it, ASAP. It’s killing my memory, slowing my page load, and causing GoDaddy to throttle my site.

    I would really appreciate if someone could offer any insight. Thank you.

  • Hi

    I went to your site and looked around (something I always do) and noted a bunch of stuff in the javascript console pertaining to google. (see image at link below)
    No ‘Access-Control-Allow-Origin’ header is present on the requested resource
    Here’s a good explanation of that issue:

    But that’s not really your problem. I just wanted you to be aware.

    Can you see if scans are running right now (like they are hung)? Have you disabled wp-cron and are using manual jobs? There’s really not a reason for that url to be called often enough for the site to tank, as far as I know. Also, do we know who 74.125.44.78 belongs to? Or is it different ip addresses every time.

    No manual jobs. I haven’t touched the wp-cron.

    The scans run, but most don’t finish if I initiate them. The automatic ones seem to.

    It’s always that 74.125.44.78. I ran it through WhoIs in Wordfence and got Google:

    NetRange: 74.125.0.0 – 74.125.255.255 [65536 addresses in this network. Click to block this network]
    CIDR: 74.125.0.0/16
    NetName: GOOGLE
    NetHandle: NET-74-125-0-0-1
    Parent: NET74 (NET-74-0-0-0-0)
    NetType: Direct Allocation
    OriginAS:
    Organization: Google Inc. (GOGL)
    RegDate: 2007-03-13

    I use PageSpeed Service for helping my page load so maybe its related to that. ?? My server at GoDaddy redirects there, and Google optimizes it. Right now I have settings for JavaScript that:

    Proxy & cache
    Inline files smaller than 2048 bytes
    Combine
    Minify

    I also use Total Cache.

    Would any of this also be causing the No ‘Access-Control-Allow-Origin’ header? I’m a bit confused by that… I don’t write any of my javascript, just have plugins.

    I appreciate your helping me fix this. It’s still hitting the site constantly.
