Ofcourse, I forgot to mention that I am using HHVM and Nginx. When I restart the Nginx server, the site is back to normal until the wee hours in the morning next day
I had similar issues, the site was ok at midnight (UK time) and down by morning…happened for 3 consecutive days…
With the below error in the logs…
Notice: Undefined index: coreUnknown in /wordfence/lib/wordfenceHash.php on line 141
Core dumped: Aborted
When I moved back to the previous version of wordfence, the site has been ok for 2 days now!
I can confirm that I downgraded to the previous version of wordfence and my site is no longer crashing.
I have the same error followed by the line
`Core dumped: Aborted
And the website is immediately down.
