Noticing that we’re getting a lot of white screens of death for logged in users and the WP Admin. Trying to isolate the issue as there is nothing in the Apache or server logs related to a specific error. However, the only way to remedy this is to restart Apache which makes the white screen go away.
The problem appears to affect a number of different WP installs so its not tied to a specific version of WP. The only thing these sites share in common is WP Supercache.
Looking further, I’m logging the errors to a log file for analysis. What I do see are hundreds of similar lines to:
[05-Nov-2010 10:22:53] PHP Fatal error: Call to a member function get() on a non-object in /var/www/vhosts/[sitedomain_removed]/httpdocs/wp-includes/cache.php on line 93
The between these errors are between a few seconds apart to 4-6 minutes. The frequency at which these appear may be cause by users leaving comments.
Has anyone experienced this before with WP Supercache?
