Excessive logging since rate-limiting turned on
This comes from https://gitlab.com/gitlab-org/gitlab/-/blob/979527db1050cb33928e5ed13b2aa8dc61d0e000/lib/gitlab/request_forgery_protection.rb#L13-15 (and yes, all 3 lines are logged) and started in earnest at 2020-11-20 02:16 UTC, which is right at the time when I clicked the checkboxes to enable RackAttack rate-limiting on production#3034 (closed). This is too coincidental to not be related.
The rate of logging is far too high to be long term sustainable (~190M logs/day, from a total of 1068M/day i.e. this added 21% to the rails logging volume).
We need to figure out why this is the case, and try to prevent it.
