Search in the /var/log/messages log if varnish it's restarting. After every crash, varnish starts answering with a 503 to every request.

Re: 503 Service Unavailable + Stop Responding
Hi, its running correct. no such messages in logfiles. Im still having the second problem, that the varnishd just stops responding on port 80 and all requests die. maybe ill switch to 2.0.4, and check it out on high load.
