Hello,
It’s been many years I have this problem. I receive daily over a dozen emails titled “Preload may have stalled” originating from wordpress @mywebsite.tld, sent by Wp-Supercache.
I made sure to go to Blog admin > WP Super Cache Settings > Preload > Send me status emails when files are refreshed, and to choose “No emails”.
But that doesn’t stop that 24/7 spam from coming in.
I’m not all for the “let’s blame the hardware or the software of the server” argument, frankly. My server runs perfectly fine multiple production high traffic websites with near perfect availability (including the blog with wp-supercache), it almost never peacks in CPU resources, it’s got always over 10 GB of spare RAM, monitoring shows the disks have perfect SMART without errors and aren’t peaking un usage.
Which leaves me with… well, no idea. Questions.
I even found a culprit, wp-cache.php, line 3596,
wp_mail( get_option( 'admin_email' ), sprintf( __( '[%s] Preload may have stalled.', 'wp-super-cache' ), get_bloginfo( 'url' ) ), sprintf( __( "Preload has been restarted.\n%s", 'wp-super-cache' ), admin_url( "options-general.php?page=wpsupercache" ) ) );
This is the ONLY line with an occurence of “Preload may have stalled”, save for the .po/mo/pot language files.
It’s as if the commands, in that line, are ignoring the “No emails” configuration option.
Please, would someone know if there’s any way to make this god-forsaken spam stop, at long last? Thank you VERY MUCH if you can help
