Impact
A large amount of page moves within a short space of time could overwhelm Database servers due to improper handling of load balancing, lack of an appropriate index on the database and the fact that updates were performed in the foreground rather than using the Jobs system.
Patches
Use any version after and including commit 48be7ad
Workarounds
You can consider other rate limit solutions like PoolCounter. Impact will vary based on usage and available resources.
