Sudden Spike in CPU, Disk and Memory Use making my website unreachable
I experience this problem a few times a week where there is a sudden spike in memory, cpu, and disk use that makes my website unreachable till i reboot.
The increase in the resource use stays up for about a minute but permanently blocks access to the website. Could this be a ddos?
Sorry i cant provide more detail unless i could attach a picture of my graphs but i think ive explained it fairly well.
