[Sat Oct 05 23:01:33 2013] [error] [client 204.*] WordPress database error MySQL server has gone away for query SELECT option_value FROM wp_options WHERE option_name = '_transient_doing_cron' LIMIT 1 made by _get_cron_lock
I check error logs for the XSS attacks but see this daily on one site. Cron is for backups I believe. I don't get daily backups from this site but I didn't realize until I noticed the errors. What is locking up the db?
