Hi,

My Hosting-Account has always a Physical Memory Usage between 600-800MB constantly . I checked the processes and there are no running processes. I found out that it could be a problem with the page cache. After I cleared the cache with the command sync; echo 1 > /proc/sys/vm/drop_caches the Physical Memory Usage went to 0 again. But after 10 minutes it was again on 600-800MB.

I have no caching plugins activated. We run on a CLOUDLINUX 7.2 Server with WHM 58 (Dedicated Server, no VM). I use Wordpress as CMS. PHP 7 and mySQL 5.6. Has anybody an idea what it could be?

Thanks
emci

Hello,

Could you elaborate if the memory usage is leading to any error messages or resource concerns? The following thread offers some additional information on memory usage you may find helpful:

Memory usage apparently higher than expected

Thank you.
