Cache clearing troubles

You’re most likely overloading your server:

If you have access to the server’s configuration files, you can try increasing the PHP memory limit:

Otherwise, you may need to upgrade your server with more physical RAM and/or CPU to handle memory- and processor-intensive tasks.

Is there any reason I’m overloading my server by trying to clear my cache with this plugin though? What separates my doing it from someone else doing it without issue, for example?

Maybe you have a tons of pages cached and when you purge (delete) the cache you overloads the server resources.

I also have the same issue, but on my site the problem occurs whenever someone edit a post and update. And then the site will be unaccessible and return 524 error.

Btw I use w3 total cache: page cache with disc basic and redis object cache plugin for the object caching.

do you have any ideas about what is happening?
thanks
