Our server backend is with play framework. During developing it seems everything is OK until we deploy it to production environment.
In production environment, the server just shutdown without any errors/warnings in logs. The last logs is like below:
2016-03-16 10:15:44,866 - [INFO] - from application in
ForkJoinPool-2-worker-1 ReactiveMongoApi stopping... 2016-03-16
10:15:44,903 - [INFO] - from application in ForkJoinPool-2-worker-3

10:15:44,958 - [INFO] - from
play.api.libs.concurrent.ActorSystemProvider in
ForkJoinPool-2-worker-1 Shutdown application default Akka system:
application
My question is: in which case would play shutdown itself? Why there is no error messages? Where should I check into first?
Thanks in advance.

can you help me please
by the way I have installed a vm under redhat
then I installed rundeck RPM
and from my physical machine when I do http: // rundecknode_ip: 4440
it returns me on the browser error 113 no route to host and on examination of the logs I have what I have posted above
when i do systemctl status rundeck it is active running
I installed kaa iot server manually on ubuntu 16.04, and use data collection sample to test how it works.
the code run without any errors, but when I run these commands below nothing happens:
mongo kaa
db.logs_$my_app_token$.find()
I even comment out bind_ip of mongodb.conf and restart mongodb, zookeeper and kaa-node services, but nothings changed.
I also regenerated SDK and rebuild project but that wouldn't help either.
finally this is the kaa log:

thank you for your help to fix this problem...
After lots of searching and checking, I finally found it!!!
there are multiple reason that this would happen:
if you are using Kaa Sanddbox make sure that you set your network setting into bridge (not NAT).
check your iptables and find out if these ports are open: 9888,9889,9997,9999.
if you are using virtual machine as your server, make sure that hosts firewall system doesn't block the ports.(This is what happened to me...)
There's an oft-asked question about changing the HTTP port to which a Play application will bind. James Ward's answer is generally accepted as the most complete, but it involves overriding the default by setting a http.port system property. However, is it possible to change this default without having to manually add it to the run command at development time, tweak the environment, or package an override in a runtime configuration?
This can be accomplished by setting the playDefaultPort key, as follows:
import PlayKeys._
playDefaultPort := 9123
Afterwards, you'll be able to run and testProd without needing to remember the desired port.
This works in both development:
$ sbt run
[info] Loading project definition from /Users/michaelahlers/Projects/MyApp/project
[info] Set current project to MyApp (in build file:/Users/michaelahlers/Projects/MyApp/)
--- (Running the application, auto-reloading is enabled) ---
[info] p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:9123
(Server started, use Ctrl+D to stop and go back to the console...)
And production modes:
$ sbt testProd
[info] Loading project definition from /Users/michaelahlers/Projects/MyApp/project
[info] Set current project to MyApp (in build file:/Users/michaelahlers/Projects/MyApp/)
[info] Packaging /Users/michaelahlers/Projects/MyApp/target/scala-2.11/MyApp_2.11-1.0.0-SNAPSHOT-web-assets.jar ...
[info] Done packaging.

I have downloaded playframework from its official website https://playframework.com/ and tried following:
activator new [appname](It has downloaded all the jar files and went through well)
on activator ui it says
Play server process ID is 4419
[info] play - Application started (Prod)
[info] play - Listening for HTTP on /127.0.0.1:8888
[info] a.e.s.Slf4jLogger - Slf4jLogger started
but however I am not access it on 127.0.0.1:8888. please help.
Thank in adv.
Play defaults to port 9000 - what you're seeing on port 8888 is activator.
Go to http://127.0.0.1:9000 - if it doesn't work, it's because you're not running your Play app.
Either...
Go the the Run view the activator app in your browser (http://127.0.0.1:8888) and cilck the Run button. If you do this, you will see the following (or similar) in the browser:
Setting up Play fork run ... (use Ctrl+D to cancel)
--- (Running the application, auto-reloading is enabled) ---
p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
(Server started, use Ctrl+D to stop and go back to the console...)
Or, run activator in console mode (on the command line, go to your Play app directory and type activator without ui). When it starts up, type run. You will see the following (or similar):
--- (Running the application, auto-reloading is enabled) ---
[info] p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
(Server started, use Ctrl+D to stop and go back to the console...)
You can now go to http://127.0.0.1:9000 to see your app.
We have a small test cluster with 3 nodes on Amazon. Everything seems working with cqlsh. But when I try to debug my app from my laptop (outside of Amazon of course), I'm getting 'Channel has been closed' errors, and it starts retrying forever. I know it's likely caused by the config in cassandra.ymal, as it shows some private IPs in my Eclipse console. Tried many different ways but still getting the same problem. Appreciate any input on this. How to get rid of the private IPs 10.251.x.x from the client?
Here are some context,
Versions:
[cqlsh 4.0.1 | Cassandra 2.0.4 | CQL spec 3.1.1 | Thrift protocol 19.39.0]

listen_address: 10.251.a.b
broadcast_address: 54.203.x.x
native_transport_port: 9042
endpoint_snitch: Ec2MultiRegionSnitch
In Eclipse console:

It seem that your Java driver is using auto discovery by calling "describe cluster" to get a list of all nodes in your cluster. In AWS using Ec2Snitch, that yields to private ips which obviously won't work from outside of AWS. There is a discussion on this topic here:
https://datastax-oss.atlassian.net/browse/JAVA-145
The last commend got my attention. It says you can do something with LoadBalancingPolicy of the driver to limit the nodes. Hope this includes specifying the specific IPs so it does not auto discover.
