503 - Resource temporarily unavailable - When Varnish Connects to Itself

It appears this was simply a configuration issue.

The default setting of min threads was 1, changing this to a higher
setting (2 was enough) appears to have resolved the issue. The maximum
was set to 1000, I never tested this configuration before because I
guessed Varnish would simply start an extra thread.

In other words, the command line parameter from "-w 1,1000,120" to "-w
2,1000,120" was enough to stop the 'Resource temporarily unavailable

We'll obviously adjust this configuration further as required.
