You are fine then. You have 867mb of free memory, with only 126mb actually used.

When you have free, unused memory, Linux will use it to cache objects. When the memory is actually needed to run programs then the cached objects are removed. Your graph in New Relic is showing you memory usage WITH buffers (line 1 in free -m). Your actual, hard memory usage is represented by line #2.

You’re fine, just disregard that graph.

thanks,Can you answer me one question? I wonder how many online customers to endure the server, when I have a $ 10 package? I have installed apache2, php5, phpmyadmin, mysql, sftpd. Thanks in advance.

I can’t possibly answer that, sorry.

Hi, you can free up your cached memory using following command -
sh -c “sync; echo 3 > /proc/sys/vm/drop_caches”

Sometimes this cached memory not releasing it because it thinks it is being used and this causes problems.
