What are the steps to problem solve when all I can get are 503s?

I'm getting the same thing on my rig.

Varnish _can't_ work with these tests failing.
The firstmost basic test checks if anything gets through by setting up
a local backend, and even this fails:
#    top  TEST ././tests/b00000.vtc starting
#    top  TEST Does anything get through at all ?

Since Jorge is running his rig fine, is there a big difference between
Solaris10 and OpenSolaris? Maybe in what kind of libc is employed?
Like a libc which doesn't have thread-safe error handling? A little
bit of debugging shows me that child creation fails due to basic
thread safety checks, the relevant line being:
