<p class="">i have a problem using varnish 3.0 and debian wheezy. When i use backend on command line, everything works. If i use init script, after some connections varnish return 503 and never can back. Backend is not a sick mode, health check still return 200, varnishlog only retorns '4 FetchError c no backend connection'.</p>
