A month ago I installed Varnish and Drupal on separate machines and could see that varnish was serving pages. A few days back I changed the ip address of the backend in my default.vcl to point to another machine and since then Varnish has stopped responding to requests. If you are wondering if I restarted Varnish, yes I did restart it.

What I find strange is that varnishlog doesn't display the ping and pong. A ps aux displays that Varnish is running. But visiting the ip address in my browser doesn't return any page.

[root@bw2 sridhar]# ps aux | grep varnish
root      3672  0.0  0.0  93660  1452 ?        Ss   10:24   0:00 /usr/sbin/varnishd -P /var/run/varnish.pid -a :80 -f /etc/varnish/default.vcl -T -t 120 -w 1,1000, -u varnish -g varnish -p thread_pool_add_delay 2 -p thread_pools 2 -p thread_pool_min 400 -p thread_pool_max 4000 -p session_linger 50 -p sess_workspace 262144 -S /etc/varnish/secret -s malloc,1G
root      5845  0.0  0.0   4356   732 pts/0    S+   10:45   0:00 grep varnish

Here is my default.vcl (if it helps). backend default { .host = ""; .port = "80"; .connect_timeout = 1s; .first_byte_timeout = 5s; .between_bytes_timeout = 2s; }

Visiting the backend ip in a browser displays pages. So I guess that Varnish for some reason has become stubborn!

  • when you restart varnish do you see any entries in /var/log/messages or varnish log?? i guess user process is not running, whats in here: netstat -tulnp | grep varnish – ADM Jun 12 '14 at 11:39
