If my server under attack?

My server some time has many connection, and overload , Load Avergage reach > 4000% !!! Normal, it work well at <100% Load

number of httpd process=4974 ( / all = 5604) | MemUsage =15564 MB/16G | LoadAverage: 4966.92, 4564.09, 4315.21

I limit 50 connection/s/IP  with port 80 by iptables

This server in group of server for download file , like mega upload...
Normal, it work well with 2000 process of httpd, but when overload, it has >4000 httpd process

And attach file log is all log connection that time!
Like in log attach file, If my server under DDOS attack?
