I stupidly requested WordFence to scan all my sites at once, and whilst they are spread across a number of servers, a couple of them crashed due to CPU and RAM issues.
I assume that when Wordfence next runs in one days time, it will likely do the same thing so I have changed the WordFence back schedule to N/A and synced my sites.
Should I re-enable the WordFence scan schedule one site at a time at delayed intervals to prevent this from occurring again? Are there any other options?
