Possibly not working with WP 3.8

@kennethkiffer,

I have been using Subscribe2 9.0 and my development code for 9.1 with WordPress 3.8 since launch without any issues.

This error seems more like a database timeout issue based on the error message. Subscribe2 will add to the time taken to make a publication and perhaps it is tipping over a server limit. Log a ticket with your hosting provider and ask them to investigate. Are you on a shared hosting plan?

I’m experiencing the same error on a dedicated server using wordpress 3.9.1 and the newest versino of subscribe2. I’m however unsure if this is actually an error or just the server reporting that it is under pressure when sending out 1000 emails?

I have checked the apache2 error log and that is not reporting any failures.

@bornakke,

This might be related to the WordPress Heartbeat API – certainly a search of the forums indicates this only started after WordPress 3.6 which introduced this capability.

You could try slowing it down a little with code like the:

/**
Slow down the core WordPress heartbeat
*/
function slow_heartbeat_settings( $settings = array() ) {
	$settings['interval'] = 300;
	return $settings;
}
add_filter('heartbeat_settings', 'slow_heartbeat_settings');
