Guru Meditation 503 Error

few causes of (and solutions to) this Varnish 503 error. Before we start One of the most confusing (but nonetheless very cool) things about Varnish is that it does not store any logs on disk. All log entries go directly into memory. This guru meditation website error allows for better performance and efficient disk usage. So to view the logs, you'll have

to fire the following command: varnishlog Once the command is running, load up a page from your website on your browser and look for how to fix guru meditation error any errors. This literally means looking for the word "error". Pretty sweet, huh! Now let's get on to our first solution. Solution 1 - General check Most of the times, Varnish 503 means Varnish cannot connect

with your backend (Apache, Nginx, etc…). So you should start from there. The first thing is to make sure your backend is correctly configured. That means making sure your Apache/Nginx/whatever is running properly before installing Varnish. If you've installed Varnish on a properly running instance, then you might just check that installing Varnish hasn't done anything funny to your Apache configurations. Here's what you can do: Open your Varnish configuration file. Mine was in /etc/varnish/user.vcl backend default { .host = "127.0.0.1"; .port guru meditation virtualbox = "8888"; .connect_timeout = 1s; } We can see that Varnish is trying to connect to port 8888 on the same machine. But is our backend responding correctly there? Let's try this (make sure you run this on your server, this port will probably be blocked to the outside world): wget http://www.your-site.com:8888 This will create an HTML file with the output in your current directory. Open the file and see if it matches your website's homepage. If it does not, then you need to configure your server. This is beyond the scope of this post, I'll advise you to check the Linode Library for resources. Solution 2 - Increase timeouts A frequent cause of Varnish 503 errors is timeouts between Varnish and your backend. This is quite easy to solve. Open your Varnish configuration file (mine was in /etc/varnish/user.vcl) and add these lines: backend default { .host = "127.0.0.1"; .port = "8888"; .connect_timeout = 1s; # Wait a maximum of 1s for backend connection (Apache, Nginx, etc...) .first_byte_timeout = 5s; # Wait a maximum of 5s for the first byte to come from your backend .between_bytes_timeout = 2s; # Wait a maximum of 2s between each bytes sent } The settings are pretty straightforward. The most important settings here is the first_byte_timeout. So go ahead and play with those settings until you find the

Thu, 2012-04-26 23:28 chritiansayers Just incase anyone has the same or a similar problem with specific file types or URL's I managed to resolve it by putting the following in our default.vcl if (req.url ~ "pdf") { set req.http.connection = "close"; return (pipe); } Replace "pdf" with a string from the URL you are having issues with, obviously in our case this was "pdf". Tue, 2012-05-29 15:54 niccottrell I'm having a similar problem but with static PDF files from the backend. On certain browsers (I think those with the Adobe Reader plugin) sometimes the user gets an error saying the PDF looks corrupted. I think it might be when the file is not already in cache and Varnish fetches it from the backend. The delay before it responds to the client might trigger some timeout. @chritiansayers: This change you made was inside vcl_pipe ?
