[smokeping-users] Smokeping crashes

[Josh Luthman]

The problem was the memory was full and swap was broken.  Some how the hard
drive had the swap partition 82 (linux) instead of 83 (linux swap). and
hence swap was zero.

Simple change of partition type with fdisk and swapon /dev/sda2 seems to
have fixed it.
