Well, the cause of the problem seems to be just the absence of the swap. In
fact, following Camaleón's suggestions, I ran `ls -la /dev/disk/by-uuid' and
noticed that the swap's uuid was different from the one in /etc/fstab. So I
edited /etc/fstab and put the right uuid, then rebooted and... the problem
disappeared! I've been testing now for a few days and and it never happened
any more. I don't know and can't imagine why in /etc/fstab there was a wrong
uuid. The same problem I had in my netbook and fixed it now. Now I have the
following output for `free -m':
$ free -m
total used free shared buffers cached
Mem: 216 135 81 0 4 57
-/+ buffers/cache: 74 142
Swap: 996 16 980
without mozilla and, while running mozilla:
$ free -m
total used free shared buffers cached
Mem: 216 209 7 0 5 67
-/+ buffers/cache: 136 80
Swap: 996 17 978
Many thanks to all who replied, and in particular to Camaleón.
