Since you are running ESXi, it is actually quite possible for it to
tell the guest (through the balloon driver) to give back some memory,
which will show in the guest as used memory.
Sorry Lennart, I don't get your point. Perhaps is because I am using the free version of ESXi and this option is not available.
Check the vmware memory statistics and see if it has done that to
the guests.
I checked it out yesterday and I found a more 'realistic' memory usage than the shown with top or free. I would like to post links containing the exported images of the charts but I don't know why some fields (the important ones) are not shown. I must go to the traditional way, printScreen + gimp...I also can post memory usage data exported in excel format if it is the interest of somebody. I will do it ASAP.
Well, I'm actually a bit confused here. I don't know in what direction should I go, I mean if I should investigate further and try to find an explanation for this or reinstall everything using a backported kernel or continuing the installation of the services and let's see what happens. Note that I am running out of time that's why I tried the official stable release because I thougth it will be pretty straightforward.
For now I am thinking to reboot every server, except Server4 which is running correctly (at least the memory usage showed seems reasonable to me), and then observe how they behave.
Thanks a lot for your help.
