A simulation of the Guru Meditation error message A Guru Meditation Error in the Nintendo DS homebrew software DSOrganize The alert itself appears as a black rectangular box located in the upper portion of the screen. Its border and text are red for a normal Guru Meditation, or green/yellow for a Recoverable Alert, another kind of Guru Meditation. The screen goes black, and the power and disk-activity LEDs may blink immediately before the alert appears. In AmigaOS 1.x, programmed in ROMs known as Kickstart 1.1, 1.2 and 1.3, the errors are always red. In AmigaOS 2.x and 3.x, recoverable alerts are yellow, except for some very early versions of 2.x where they were green. Dead-end alerts are always red and terminal in all OS versions except in a rare series of events, as in when a deprecated Kickstart (example: 1.1) program conditionally boots from disk on a more advanced Kickstart 3.x ROM Amiga running in c

Guru Meditation Error Virtualbox
on September 18, 2014 by vonnie — 12 Comments ↓ I have guru meditation error 503 a penchant for VirtualBox because it gives me a playground for experimentation. I can intentionally install viruses in the

virtual machine (called the guest OS) with little fear of my real computer (the Host OS) getting infected. I can install entire virtual networks with little trepidation of breaking my https://en.wikipedia.org/wiki/Guru_Meditation real network. And I can test out different operating system before changing my Host OS to that OS. It's great. But the other day something odd happened after I spun up my VM… The guest OS launched fine, well for the first 10 seconds, but then it unceremoniously burped up an error about Guru Meditation? If you've ever seen this error, it's http://www.fixedbyvonnie.com/2014/09/heck-virtualbox-guru-meditation-error/ pretty disconcerting and hard to dismiss. You only have two options: You can click OK or hit Ignore but both usually return the same result: the application quits. When you launch it again, it barfs up the same rude error you tried to avoid. Some crazy spiritual stuff about a meditating guru. What's all this about? Getting spiritual with Guru Meditation The first time I ever saw this error, I envisioned a Tibetan monk, perched on his aerie ledge in the Himalayas. His legs are crossed Indian style and his wrists are propped face-up on his knees. I don't know why but that's the first thing that comes to my mind. I did some research on this and it turns out the phrase "Guru Meditation" finds its origins from one of the first personal computers called the Amiga. Sold by Commodore in the mid 80's, these relics of time would sometimes spit up Guru Meditation errors on software failure. Guru Meditation refers to an error so arcane that you were basically forced to look for a Guru to fix the problem. Today, you going to help
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 http://www.technoreply.com/solving-dreaded-varnish-503-error/ into memory. This 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 http://stackoverflow.com/questions/9244932/varnish-guru-meditation on your browser and look for 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, guru meditation 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 guru meditation error was in /etc/varnish/user.vcl backend default { .host = "127.0.0.1"; .port = "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.
