  Hi @kamall, I apologise if this sounds silly, but do you have firewall set up on your server? Peter

  use netstat command and check how many connections are there on port 80. If connection is too high then it seems that server is under attack. You have to tweak apache settings and install firewall and DDOS protection tool.

  Hello, I suggest starting with the following thread, as mentioned earlier: Troubleshooting High Loads On Linux Systems It should help give you a better idea of what's causing the high load. Thank you.
