Sudden increase of CPU and outbound connection
It's already a few times that this issue happened to my droplet. It seems that randomly the droplet start using 100% of the CPU and a big quantity of outbound bandwidth causing my server to slow down, then after some time (usually a few hours) the droplet instantly gets back to a normal situation. It's a very strange issue, i tried to monitor the processes and the outgoing connections but i can't see anything of unusual. I also tried to shutdown and restart the machine while I was having this issue but I couldn't fix it.
Do you have any idea why this could happen?
(I'm running lemp on an ubuntu machine)
