CentOS 7 low memory

[pma61]

Hi!

I have a CentOS server with 4 GB of RAM.
When the server finish the boot, he used only 800 MB of RAM, but after few hours I have this problem:

Code: Select all

[root@home TEST]$ free -mh
             total       used       free     shared    buffers     cached
Mem:          3,7G       3,6G       127M        17M       887M       1,9G
-/+ buffers/cache:       862M       2,9G
Swap:         3,9G         0B       3,9G

How can I found the process that uses too many RAM?
Thanks!
