    STH has been really slow lately. It turns out that there was a bug in WordPress 4.3.0 that was causing a ballooning query on every page load:
    Also saw
    mysql> select * from wp_options where
    ERROR 2020 (HY000): Got packet bigger than 'max_allowed_packet' bytes
    And a lot of
    Fatal error: Allowed memory size of abc bytes exhausted (tried to allocate xyz bytes) /wp-includes/wp-db.php 
    Even the giant boxes running STH were feeling the weight of the what became 100MB query, on every page load. I am sure if @dba sees this he will cringe.

    Just wanted to give a quick shout out to Steven @ Rack911.com ( Linux Server Management, Linux Server Security, Linux Disaster Recovery | RACK911 ) for helping figure this one out. I think within a few minutes he found others with similar issues.

    It is an absolutely crippling bug even with big/ fast processors, SLC SAS SSDs and lots of RAM. The new version came out today (Sept 15, 2015) but it was too late for STH as the back-end had already became inaccessible. Thanks to the help of Rack911 this got resolved.
