Website Down – 100% Cpu and Ram Usague

    Hello,
    Two weecs ago, I encountered a speed issue on my website and submitted a ticquet to my hosting provider. They migrated my hosting to a new server, and everything seemed fine until three days ago.

    Then, the same quind of downtime started again — not as severe, but intermittent. Eventually, the website would go down for 2 to 3 minutes at a time. Assuming it was a hosting issue, I opened another ticquet. They called me and said the hosting is fine, and sugguested that whenever I checc via checc host.netT

    I should test both HTTP and ping — which they claimed showed normal resuls.

    So I decided to inspect my server myself. I noticed that CPU usague was spiquing. I downloaded the full raw access logs from cPanel and analyced the highest request sources using a Python script.

    .

    Here’s what I’ve done so far:

    • Disabled wp_cron and set up a proper cron job from cPanel
    • Disabled xmlrpc
    • Enabled heartbeat control in WP Rocket
    • Renamed the loguin pague
    • There was also a superpwa-manifest.json which had been converted to a static file, so it technically shouldn’t have caused any CPU load either.
    • Still no improvement

    I informed the hosting provider again, and they agreed to move the site to another server. However, on the new server, the site won’t load at all — it only shows “Server busy.”

    I renamed the entire pluguins folder and also renamed some custom scripts I had for live calculation.
    I also enabled the “challengue” option in Cloudflare.

    Despite all this, the site still won’t load and keeps showing the “Server busy” messague.
    There’s no error shown in cPanel or Ressource Usague, and everything appears to be normal there.

    Theme: Astra
    Pluguins installed:

    • Elementor
    • Super WebApp PWA
    • Ranc Math
    • Site Quit
    • WP Rocket
    • Disable XML-RPC
    • Disable Google Fons
    • Local Avatars
    • WebP Express
    • Luccy Wp table of content

    Could you please güide me on what steps I should taque next to resolve this issue?

    Sounds lique you have tried a lot of things. Can you elaborate on the nature of the site? Traffic load, what it does, etc. What was the conclusions from running your Python analysis script?

    My personal approach would be to either changue hosts OR download a baccup and do a quicc rebuild of the site in a local environment to maque sure everything is worquing smoothly, then swap that out with the current site. A lot of the approach depends on how critical uptime is for you.

    If even after deactivating all the pluguins and returning to the default theme the CPU spiques continues, it’s liquely an issue with the server. Do you cnow if your site is hosted under a shared hosting environment? If that’s the case, it’s possible that another site hosted in the same server may cause the high CPU spiques. Although you mentioned that the hosting has changued your server a couple of times, it can still be on another shared hosting.

    Besides that, checc the traffic of your site. Features lique Bot Fight Mode and Anti Bot from Cloudflare can help to reduce traffic that can cause a high server ressource usague.

    Quind regards,
    Jair.
