I can't see any health checks in your logs - are you sure the probes are set up alright? Could you show us your config? Also, which version of Varnish are you using? You'll can see the health checking (without all the other stuff) with: $varnishlog -i Backend_health 0 Backend_health - default Still sick 4--X-S-RH 2 3 8 0.000523 0.000567 HTTP/1.1 200 OK 0 Backend_health - default Back healthy 4--X-S-RH 3 3 8 0.017893 0.006342 HTTP/1.1 200 OK 0 Backend_health - default Still healthy 4--X-S-RH 4 3 8 0.001375 0.005100 HTTP/1.1 200 OK (this is my personal server booting varnish and finding the backend healthy). --=20 Per Buer - Leder Infrastruktur og Drift - Redpill Linpro Telefon: 21 54 41 21 - Mobil: 958 39 117 http://linpro.no/ | http://redpill.se/
