setting varnish storage size

[Poul-Henning Kamp]

The limit is in the CPU hardware:  with 32 bit address bits you
can only see 4GB of RAM at any one moment.

Usually operating systems and (PCI) devices eat up 1-2 GB of the
4GB, and you also need space for the program, shared librararies,
stack and other data.

Get a 64bit machine.
