Varnish restarting sporadically... losing entire cache...

[Per Buer]

Hi.

Note that you are running on a 32 bit platform. You could easily be
running out of virtual memory. We recommend you only run on 64 bit at
least for production. I guess that if you switch platform the problem
will automatically go away.
