I've all of a sudden started getting this error when creating users in my app. Emails were working before I left for vacation, now I come back and this is what my tech support gives me! Ugh.
So, I make a user, and I get redirected to my admin panel with the following error in a flash notice: getaddrinfo: name or service not known. The user isn't created.
Looking at the logs, it looks like everything worked fine:

I've filtered the email address but, rest assured, it's a valid email.
I'm using EC2 to host my application, so I can't edit /etc/resolv.conf since any changes will be overridden.
I've run nslookup to make sure the server can find the domain MX records, which it does using the nameserver specified in /etc/resolv.conf.
What else can I do to troubleshoot this issue?
I used a recommendation I ran across on another blog to use Ruby's version of Resolv instead of the libc library with Ubuntu. So, I added the following line to an initializer: require resolv-replace.rb.
Now my error is a little more descriptive: Hostname not known: smtp.sendgrid.net, so I checked config/environments/production.rb and it turns out I had a trailing space at the end of my host line. Removed it and all is working now!

I have a Rails app that works perfectly in development. I have deployed to the server and the app loads and correctly shows its landing and about pages. However, when I go to a page with Action Cable, the server blocks. The last request out from the web page is Action Cable related, and further page actions (form submission, and even reloads) and not responded to.
I have isolated it to the server as attempting to load the site's main page from another browser does not work. Closing the tab where the request to Action Cable was first made results in the other page loading immediately (and all of the pending requests from the first page suddenly being processed).
I do not see any errors in production.log, but here is the part leading up to the hang:

Once I close the offending tab, load continues (in this case, of a javascript request that was triggered on page reload) as follows:

I've truncated the remainder; there were no failures or anything else of interest in there.
I do have a redis server running on the same server and have put its port information into config/cable.yml under the production: section.
I believe that Rails can see it as I haven't seen any errors. Additionally, to verify this I connected to redis through redis-cli and subscribed to a channel, and then through the Rails console sent a broadcast message to that channel and verified receipt.
Update: I've tried a few different builds to isolate the issue. Here's what I now know:
I removed my only call to ActionCable.server.broadcast, so that isn't the source of the block.
I added javascript console logs to connected, disconnected, and received. The client does successfully subscribe.
I tried a build where I removed the App.cable.subscriptions.create from the client. While there is no websocket connection in this case (as you would expect), the server does not block/hang.
Given the above, I am certain this has to do with ActionCable, though I'm not sure if it has anything to do with my redis configuration.
This turned out the be the behaviour you get if you haven't set the following lines inside of your nginx conf file (inside of the server section):
location /cable {
passenger_app_group_name your_app_websocket;
passenger_force_max_concurrent_requests_per_process 0;
}
where, if your app name is "chat", the first line would read:
passenger_app_group_name chat_action_cable
Which, frankly, I'm not sure where is defined, but it may be part of the Rails magic.
I am using Nginx & Phusion Passenger for running Rails app. I got these errors in the access log:

I tried to search the IP 61.160.213.56 over the google, I found this page: http://www.ipillion.com/ip/61.160.213.108
It said that: 61.160.213.108 is known for firewall alert, port scanning.
Could any one tell me what does it mean? Do I need to block this IP from my site?
It's port scanning, and sending lots of dummy URL which could be allowing attacker to login to Admin page.
I've seen the same ip using the same URL. Here are a few more similar IPS doing the same thing:
61.160.213.55
61.160.213.56
61.160.213.247
61.160.213.32
I have updated my Remine on servers from 2.3.0 to 2.4.1 and one (and only one of them) stops sending mail. If I was switched it back to 2.3.0 version, all works fine.
I am going to try to debug the code and just wondering which file in source code will be a good starting point to it ?
I have found notified_users(), recipients(), each_notification() in Issue model, but where is a code line which send email ?
Updated:
When I edit issue I get next message on console:

I think you should look at app/models/mailer.
For example notified_users is used here
If update breaks sending emails I suggest to review config files, for example config/configuration.yml.example and check fresh issues on redmine.org
Here's a snippet of my production.log:

As you can see, it's logging two concurrent sessions of two different users simultaneously to the same log file. This makes it impossible to parse my logs and determine, for example, the time it took to generate each kind of page, because the entries are not in the expected order of:
Started GET "/URL/BLAH" for IP at DATE
... stuff...
Completed 200 OK in XXms (ActiveRecord: YY.Yms)
Instead I get an unpredictable interleaved log like this:
Started GET "/URL/BLAH" for IP at DATE
Started GET "/URL/BLAH" for IP at DATE
... stuff...
Completed 200 OK in XXms (ActiveRecord: YY.Yms)
...stuff...
Completed 200 OK in XXms (ActiveRecord: YY.Yms)
So it's impossible to match the "completeds" with the "Started."
What I'd like is a way to have each child process write to its own log or something. Or if it's possible a way to write the each pageview's log atomically, but that might be impossible or difficult or hurt performance.
Rails 3.2 provides nice option config.log_tag
You can add to your production.rb:
config.log_tags = [ lambda { Time.now.to_i }]
So each line in your logs will be prepended by numbers. Example:
[1351867173] Started GET "/" for 127.0.0.1 at 2012-11-02 16:39:33 +0200
[1351867173] Processing by RecipesController#main as HTML
Logs are still shuffled, but now we can normalize, order them.
sort -f -s -k1.1,1.11 production.log | sed 's/^.............//' > sorted_production.log
(Sorter by first symbols (by timestamp) and remove timestamp by sed)
Now logs are easy to analyze.
In addition there is fix on related issue https://github.com/rails/rails/pull/7317 in rails 3.2.9
So keep this in mind.

I tried out rails 3, and just started a new project. The following is all I typed.
rails new todo
cd todo
bundle install
rails generate scaffold Task done:boolean task:text created:date
rake db:migrate
rails server&
firefox 0.0.0:3000/tasks&
On page 0.0.0:3000/tasks/new, I filled in some values for the fields, and clicked the button to create a new task. It redirects to 0.0.0:3000/tasks with a blank page. When I manually reload the page, it shows up eight tasks even though there is supposed to be only one.
When I further click either show, edit, or destroy, it says, for e.g.: ActiveRecord::RecordNotFound in TasksController#show Couldn't find Task with ID=1.
When I reload to 0.0.0:3000/tasks, all eight tasks are still there.
What is wrong with this? Is rails corrupted on my computer?

You're trying to access your site using 0.0.0:3000 which is an invalid address (I'm actually surprised this even gives you access to the site at all).
Open 0.0.0.0:3000 in Firefox instead, and it will work perfectly!
(You can also use localhost:3000 or 127.0.0.1:3000)
Task is a reserved word in Rails. I guess thats the reason why rails is behaving in a starnge way.
For a list of other reserved words please refer to any of these links
