Today (Saturday), have made some MySQL configuration changes, which I hope will help mitigate DB issues when hit by "rogue bots" who do not "follow the rules" (robots.txt).

That's all the MySQL DB changes for this weekend.
 
MYSQLND_MS_XA_COMMIT(3) 						 1						   MYSQLND_MS_XA_COMMIT(3)

mysqlnd_ms_xa_commit - Commits a distributed/XA transaction among MySQL servers

SYNOPSIS
int mysqlnd_ms_xa_commit (mixed $connection, string $gtrid) DESCRIPTION
Commits a global transaction among MySQL servers started by mysqlnd_ms_xa_begin(3). If any of the global transaction participants fails to commit an implicit rollback is performed. It may happen that not all cases can be handled during the rollback. For example, no attempts will be made to reconnect to a participant after the connection to the participant has been lost. Solving cases that cannot easily be rolled back is left to the garbage collection. Note Experimental The feature is currently under development. There may be issues and/or feature limitations. Do not use in production environments. PARAMETERS
o $connection - A MySQL connection handle obtained from any of the connect functions of the mysqli, mysql or PDO_MYSQL extensions. o $gtrid - Global transaction identifier (gtrid). RETURN VALUES
Returns TRUE if the global transaction has been committed. Otherwise, returns FALSE SEE ALSO
