   I am trying use WP Super Cache plugin but keep getting this error message:

   "Cache expiry cron job failed. Job will run again in 10 seconds."

   I am seeing this in multiple WordPress installations on multiple servers. Anyone know what could be causing this message and how to resolve it?

   Are you using coarse file locking? That's usually the reason this fails.

   No, I'm not. The box is unchecked.

   Best thing to do is open wp-cache-phase2.php and find the warning, "Cache expiry cron job failed". There's a line above it:
   if( false == ( $num = wp_cache_phase2_clean_expired( $file_prefix ) ) ) {

   Change that "==" to "===". Does that help?

   If that doesn't change anything look at the function wp_cache_phase2_clean_expired and check the return values it returns.
