We have couple of servers. nginx takes the web requests


Active connections in the range of 400-450 is okay

but sometimes it goes to like 4,000. at this point in time. This is abnormal

What does this mean? Is it that nginx is not able to take the load?

Or is it that the DB Server behind nginx is taking time? Or is it that the Ubuntu server is not network optimized? Or is it that the RAM is low?
