Question
100% CPU load (non-stop), out of the blue. Droplet is stuck ... what to do ...

Asked by Lex Gabrees
So, I’ve got this droplet running for around 3 years. It’s been running fine, but suddenly today, it’s not responsive.
The droplet is in NY3
I can’t get to the wordpress site that’s installed, and I cannot get through on SSH. Sometimes it works, but it’s incredibly slow …
I was able to get to htop and it showed me that there’s a 100% CPU load.
When I turn off the droplet and the start it again, it works for about 1 minute, before getting back to the problem situation.
This thing was working perfectly yesterday, and nothing happened between then and now …
Any tips on how to proceed ?

Hi there,
It sounds like that you might be getting a spike in the traffic. What I could suggest is:

Check your Apache access lots to see if you are not getting any malicious traffic or a brute-force attack. You can use the following script to summarize your access logs: BASH Script to Summarize Your NGINX and Apache Access Logs
Do some general optimizations like: disable and delete all plugins and themes that you do not use, install a caching plugin like WP Super cache. Use a CDN like Cloudflare
Let me know how it goes!
Best,
Bobby
