Or, you could use WP-CLI which was developed for scenarios like these. After a short installation like this $ curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar $ chmod +x wp-cli.phar $ sudo mv wp-cli.phar /usr/local/bin/wp You can run your scheduled tasks like so $ wp cron event run –due-now –path=/var/www/mywebsite.com/ or via crontab (every 5mins) */5 * * * … Read more
Yep, this does seem like a cron issue. Core Control plugin is good to diagnose cron tasks (among other things). I am still unsure what is the reason of you getting overrun with feed transients. However I had written some code that might help with automatic cleanup.
wp_cron is used to schedule tasks such as deleting old posts from trash, deleting old spam comments, and checking for plugin/theme updates.
The first step is setting up the cron job. The second part requires querying the database for a specific post type where the entry is older than 1 week. We can do this with get_posts() and specifying the category argument and the date_query argument. //* If the scheduled event got removed from the cron schedule, … Read more

Create a function to truncate posts This can be used for both methods below WP-cron or UNIX cron. function foobar_truncate_posts(){ global $wpdb; # Set your threshold of max posts … Read more
An idea I came up with was using the new WP Heartbeat API as opposed to using cron. Have your plugin fire off a call to your logging system every hour. Pippin’s tutorial contains the majority of the code you’ll need to get started.
Try this instead: $gloabl $myxclass; $myxclass = new Xwidget(); add_action( ‘xxx_followers’, array(&$myxclass, “cron_addB” ) ); or add_action(‘xxx_followers’, “init_xclass_and_cron”); function init_xclass_and_cron() { $myxclass = new Xwidget(); $myxclass->cron_addB(); }
You have to schedule your event in a hook, for example in after_setup_theme or wp actions: add_filter(‘cron_schedules’,’my_cron_definer’); function my_cron_definer($schedules){ $schedules[‘twomin’] = array( ‘interval’=> 120, ‘display’=> __(‘Once Every 2 Minutes’) ); return $schedules; } add_action(‘my_periodic_action’,’my_periodic_function’); function my_periodic_function(){ mail(’[email protected]’,’Test!’, ‘Test Message’); } add_action( ‘wp’, ‘wpse8170_setup_events’ ); // or add_action( ‘after_setup_theme’, ‘wpse8170_setup_events’ ); function wpse8170_setup_events() { if ( … Read more
For Q1 – One for each path / site. Each site has its own cron (jobs) internally. So, it is possible to fine-tune the frequency. For example, a low-traffic site may not have lots of cron jobs. So, the cron could be executed less frequently than a site that requires frequent updates. For Q2 – … Read more
Cron tasks don’t directly affect page load besides the 0.01s timeout (of course, they do affect server load, so they can impact page load indirectly). My hunch is that your PHP config is the issue. The cron tasks run like any other web request, and they’re subject to PHP’s max_execution_time INI setting. If this is … Read more
