    wp-cronp.php is using 10% of my mediatemple GPU current usage (not 10% of my quota).

    I would like to understand know. I would like to know what is wp-cron.php doing in a wp install. is it something related to the scheduled posts ?

    Thanks in advance !

    Hi

    Not an authoritative answer, but here is a plugin that lets you monitor scheduled WP cron jobs.

    I'm also a bit confused here. I thought WordPress already has a cron system built in. There is hardly any info on the front page for this plugin.

    Should this plugin be used as a replacement to the existing wp-cron?

    no, aicos.

    the plugin page says,

    This plugin adds a page in the admin area where you can see all the queued Cron events, when they are due, which schedule they are on (or if they are one off) and which hook they will call. Future development might include:

    * Removing Cron events
    * Seeing which functions/methods are currently called by which hooks
    * Manually adding Cron events
    * Editing Cron events

    It does exactly what the OP wants -- to see what wp's cron is doing.

    ok, thanks for the explanation. When I said the plugin page, I mean't this one:

    http://wordpress.org/extend/plugins/wp-cron/

    All it says is - periodic execution of actions.

    So the question remains unanswered -- what is it doing being executed so often? Is this an attempt to hack my blog? Should I do something to cut off the huge amount? I got 31000 hits to wp-cron last month, or 11% of my pageviews. I don't use the "publish post in the future" feature often, so there's not much of a reason for the system to be doing anything there.

    Checking stats back in April wp-cron was not used at all (or at least didn't hit the top 10 page accesses)

    cron's are scheduled stuff
    db back ups, email postings

    I just checked my server log, and all accesses originate from my server, so it's something that is used internally to WP and not some kind of hack attack.

    In my Wassup plugin to see who is on, it showed:

    65.254.224.36 2010-01-27 00:27:10
    /wp-cron.php?doing_wp_cron

    So it labeled it as spam? I get a lot of these direct access to this crom, and at the stop forum spam website the IP is shown as a known spammer IP.

    yeah, I recently installed the Ultimate SEO plugin which has a 404 error log. Since I recently changed my permalink structure (big mistake), I've been monitoring it.

    I get about 100 -200 "/wp-cron.php?doing_wp_cron" showing up as a 404 error (with my website domain preceding it) per day.

    I'm not sure if this is spammers or if I've created a problem using the redirection plugin. Any way that I can find out?
