I'm running WordFence 5.0.6 with Falcon Engine on a WordPress site which was automatically updated from 3.9 to 3.9.1 about 24 hours ago.
Really happy with the performance but I just got a warning from my hosting provider that I had exceeded my storage quota.
cPanel told me
wfcache size: 562.57MB (589901824 bytes)
I have a 1.2TB allowance so wfcache was using nearly half.
As this is a production site I was worried that functions might start failing, so I quickly cleared the Wordfence cache without attempting any debugging.
Could a crawler which tried to visit every page of my site have caused the cache to grow so large?
Is there a way to limit the size of the wfcache?
