I'm hoping someone can lead me in the right direction of how to track down this problem. I recently had HHVM installed on my server with PHP as a fallback. Since then I've been having issues in WP admin.
When I attempt to post or update a post my connection times out at 2m and in my NGINX error log I see this:
recv() failed (104: Connection reset by peer) while reading response header from upstream, client
What I can't figure out is why it's happening to me but not to my server management service or to my writer who have both tried and not had this problem.
I've done a traceroute and ping to my server and there's no latency issues showing up. I've tried different browsers, I've changed my DNS, and I've tried connecting through a VPN and I still have the same problem. I don't have any problems other than that.
This is a dedicated server with plenty of resources available and it only started after HHVM was installed. The admin panel became very slow until Redis was installed but that didn't help the issue of timing out. I didn't initially time out but now I can't post or update without timing out but the data does get saved to the DB.
Are there any other ways I can track down what the problem might be or any ideas on what the problem could be?
