Please post your email as plain text and not HTML. Having timeouts that high is usually a bad idea, as you don't get the log segments back from the worker threads before the timeout goes off. Two minutes is a long time to wait while debuging an issue. To get help with this you need to extract varnishlog for the 503s and post that. -- Lasse Karstensen Varnish Software AS _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
