Sander's questions

My VPS is using much RAM. To identify the problem I stopped literally every service, the VPS is still using 4.5GB of RAM. The VPS is running on XEN, so the RAM is not shared.

This is the output of free -m after stopping all services (except ssh):

[root@node3 ~]# free -m

             total used free shared buffers cached

Mem:          6928 5510 1417 0 130 704

-/+ buffers/cache: 4676 2251

Swap:         3071 106 2965

Could someone help me with this? Many thanks.

I have about 200 directories in /home/. The problem is that they all exist in this way:

/home/{user}/homedir/

While it should just be:

/home/{user}/

With what command can I mass move all content of homedir one directory up for each user?

Thanks for the help.
