I don't know enough about MySQL to know if it is or not. This does not
at first glance seem to be related to innodb_buffer_pool_size however.

AFAIK AWL grows forever. Something like this may help somewhat:
DELETE FROM `awl` WHERE `count` = 1 AND `totscore` > 5;

I see you are on the Postfix list so you are in good hands. I hope

surface it appears some servers are really getting hammered.
