This plugin will check your posts, comments and other content for broken links and missing images, and notify you if any are found. (non-commercial community fork of broken-link-checker)
the plugin is altering the PHP environment values and this is a pretty serious intervention in the environment. May want to somehow change how this is set up. Or throw more warnings if it is engaged. And per this report it happens even if the plugin is not active. (given the better batch handling in the fork this may not even be needed anymore. the jobs seem to move along okay without these extreme settings, that can cause other problems elsewhere)
