Sysinstall defaults to creating a swap partition that is 2x RAM, but
for large-memory systems it's usually overkill (do you really plan on
running 3gb worth of processes in a 1gb system?). 1x RAM is the
minimum if you want to be able to save kernel crashdumps though, so it
may be useful if you ever double the RAM in the box.

Run ps axl, find the parent process (PPID column), and fix the bug in it :)
