XF 1.3 Users awaiting approval page throws 504 Gateway Time-out

[Joshua]

I have ~100 users waiting to be approved/denied for registration and when I click to view the list in the ACP, I get a "504 Gateway Time-out" every single time.
Any tips on what server parameters I can change (probably for nginx) to get around this? I'm guessing it's a memory issue?

Try raising
send_timeout 60s; in nginx.conf
