Every so often, I get the following it did not write a startup response in time. error, but it is unpredictable and rights itself a few minutes later with no actions taken, so it is extremely hard to debug: Internal server error Phusion Passenger has listed more information about the error below. An error occurred while starting the web application. It sent an unknown response type "". Has anyone else run into an error like this, or know what it could imply? apache postgresql server passenger linode share|improve this question edited May 7 '15 at rails internal server error 19:05 asked May 5 '15 at 17:16 Joe Morano 13711134 Memory issues? What's the size of your Linode and is there any free memory left when you get this error? –Capsule May 8 '15 at 1:12 @Capsule My linode has 0.5 gb of RAM. There's no Swap Memory left when I get an error, but there is usually around 20000k Memory left. Which is odd, because I thought Memory ran out first, and Swap acted as a backup... –Joe Morano May 9 '15 at 18:46 It's possible the kernel reserves some memory so the system doesn't crash, but you obviously have no memory left for applications once you've reach the bottom of the swap. Anyway, even if your applications were able to use the remaining 20MB, it's not much at all and you'll run into some major problems sooner or later. Try increasing the swap as a test (even tho Linodes run on SSDs and it won't be as terribly slow as if you were swapping on an hard drive, you should consider getting more memory) and see if the error goes away, or happens less often. –Capsule May 11 '15 at 3:33 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote Firstly go through this question, as it might solve your problem: Passenger: internal server error There are possible causes of problems

I've had it working before, but after re-deploying via Capastrano I am unable to get it going. Here are the facts: The server is setup with nginx + passenger, and I'm using PostgreSQL. Static assets are working properly, as in I'm able to access them just fine in a browser. I can access the rails http://stackoverflow.com/questions/9970028/how-to-properly-diagnose-a-500-error-rails-passenger-nginx-postgres console via RAILS_ENV=production bundle exec rails console and perform Active Record actions (like retrieving data from the db). Within console, I can run app.get("/"), which returns a 500 error as well (after first showing the query that was run to load the model). The production.log file is never written to. I've set permissions 777 on it just for the hell of it. I've also set the log level to :debug with nothing to show for it. The nginx log (which passenger also uses) shows no indication of errors, it just notifies about cache misses. Because nothing of use is being logged, I have no idea what to do here. I've tried setting full permission on the entire app directory with no help. Restarted the server multiple times, nothing. The database is there and rails can clearly communicate with it. I'm not sure what I did to get it to run the first time around. I just don't know why rails isn't outputting anything to the log. ruby-on-rails ruby-on-rails-3 nginx passenger capistrano share|improve this question asked Apr 2 '12 at 1:49 Brian 1,95442247 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted Okay, I figured this out.

The server is running phusion passenger (even though I am not getting that internal server error error message anymore) and in my local test environment everything seems to be working fine. Here is the site: http://www.pandonews.com/ When I looked in my apache log i see this error: [ pid=3106 thr=140057117177664 file=ext/apache2/Hooks.cpp:884 time=2013-09-01 17:37:24.84 ]: Unexpected error in mod_passenger: Cannot spawn application '/var/www/feedme': The spawn server died unexpectedly, and restarting it failed.

It has been running fine up until now. I don't really know where to start in order to fix this. I tried running gem passenger install again but nothing happened. Recent activities: Installed pg gem (but removed it from gem file after deciding to stay with sqlite3 for now) the yml file should be ok... Tried running bundle update on server and locally but it keeps hanging Changed some javascript and css files... Tried resetting the server with RAILS_ENV=production rake:db reset - no change! EDIT: when running rails s production i get the following err

I'm not sure if my expected behavior is correct, but other application servers(webrick, unicorn) behave that way. Any thoughts? FooBarWidget added the Bounty/Easy label Jun 14, 2014 Phusion B.V. member FooBarWidget commented Jun 14, 2014 I don't know from the top of my head what's causing this. This issue needs further investigation. namusyaka commented Jun 14, 2014 According to error.log, passenger has allowed to pass the invalid query to my application. Other servers seem to deny it on the server level. I think passenger should deny the invalid query, and return the bad request. aganov commented Feb 4, 2016 Invalid requests are reaching our application too, causing error log to be clogged with Rack::Utils::InvalidParameterError: invalid %-encoding (%s). I think passenger should return 400 Bad Request, and the rack app should never been reached... More information can be found here: rack/rack#337 Our env is ruby 2.2.3 and passenger 5.0.20 with nginx FooBarWidget
