Hi all. About a month ago my site managed to crash the VPS we were on and I had to move to a new server. For once I paid someone on here to transfer and optimize the site. As far as I understand, we went from an Apache-based vbulletin install to one running off of nginx, but Apache is also running on the new server.
This was a month ago, and for the month the site has been running fine. Then yesterday I had nearly two hours of downtime across the entire site, with a 502 Bad Gateway error from nginx. Today at roughly the same time, it appears to be happening again. I haven't made any changes to the site, but our traffic has been a bit higher in the past couple weeks. I'm on vbulletin 4.1.4 CMS Suite with several modifications installed (several from DB-Tech, plus DownloadsII plus vbSEO plus vaultwiki for the heavy hitters).
So now I have to ask for advice, how can I track down and eliminate the source of this problem? I'd like to not have daily downtime if these keeps up. I'm really new to using nginx so I don't know how to handle these errors yet.
