    I had to deactivate the plugin and now everything cools down.

    The new version causing this issue? It wasn’t like this before.

    Hi @zakirstage,
    This is very unusual as @salvatorefresta has many cloudways server and we test the plugin thoroughly before releasing. It is being used in many cloudways server without ever having this issue. The plugin is quite light with very little resource usage. The entire plugin was designed keeping performance in mind. I think something else might be causing the issue. I think you should talk to cloudways to track down what was eating the resources.

    Just a few note, inside the fallback cache, were you using cURL mode?
    Also, were you preloading a lot of URLs at a go?
    The reason I ask this is that all of these operations use cURL which can take a little resource to execute. Besides, there is nothing many resources intensive.

    @salvatorefresta do you got any ideas?

    No I wasn’t use cURL method. I just put the api key of CF and then enabling page caching and then it starts.

    What I noticed, after I activated the plugin, whole site getting slower, and then I logged in to Cloudways and checking the our site status.
    Ram increased 7 out of 8GB
    CPU 70% and then 80% out of 100% and went to 100% and then I couldn’t access mysql, phpmyadmin. The error message in front-end: Error to establishing database connection.

    Our usual CPU 7% and RAM 3.62 out of 8GB.

    It was never like that as we don’t have literally no traffic.

    Then I renamed the plugin via FTP and deelted the one folder that plugin created in wp-content and remove the rules in htaccess file that plugin created. After few minutes to wait i can see CPU, RAM was cooling dow and then I deleted the plugin and deleted the plugin options fields from database.

    Now everything is fine.

    Same thing happened in december and I talked to Cloudways support, they didn’t exactly identified which plugin as new relic was not enabled in cloudways. That time i had to rename the plugin folder and then i had to create another plugin folder and move all plugins and gradually enabling them one by one. And all restored.

    Today I thought lets install your plugin and then it start causing this issue.

    Regarding preloader, I didnt have the chance to change anything as I was not able to access as CPU went high.

    Guys I need your plugin. Is there any way you can help us? I can share the login details of everything (WP, Cloudways, Cloudflare).

    Hi @zakirstage ,
    you should enable the log mode in high verbosity. If something triggers the cache purging may times at once, you can see it into the log file.

    I am closing it as I believe this is specific to my particular site. but we have another site where it does not have this type of issue.

    Thank You guys.
