I notice a difference between the memory usage shown by Webmin and by the command free -m
Webmin says :
Real memory 3.83 GB total, 350.07 MB used
Free tells me :
[root@server at]# free -m
total used free shared buffers cached
Mem: 3923 1747 2176 0 245 1160
-/+ buffers/cache: 341 3581
Swap: 4031 0 4031
Which one is accurate (probably the command 'free') ?
Why does Webmin then not show correct memory usage ?
