Depending on the services running on your server and the number of visitors your server is getting, this might be correct. But you might also be interpreting the numbers incorrectly, it's a common issue. So, before going deeper into the problem, let's establish what's going on.

Please log in to the shell of your server and post the output of the command:

free

Take into account that RAM used by buffers/cache is only used to speed up your server and would be automatically freed if needed by programs. You should consider it as free.

If your actual RAM usage is indeed high, please also post the output of (the command will display top 30 processes that use the most of the resident memory, in kb):

ps axo pid,rss,comm=|sort -n -k 2 |tail -n 30

If you'd like to see the entire list, run:

ps axo pid,rss,comm=|sort -n -k 2
