Faithfully yours, nginx.
No I recently upgraded a phpbb database for a subforum on my nginx server, and this has only started happening since then. It seems to appear randomly and go randomly. I've tried restarting the nginx server but it doesn't make a difference. It is affecting the whole nginx server too, not just the subdomain I upgraded.
Can you help me out with some initial things to look for? CPU usage, which error log to analyse, etc? I'm not really sure where to start with troubleshooting this!
The only upgrade I did was phpbb3 to phpbb3.1 (mySQLi)
Thanks!
