Hello! I'm receiving 503 error after service restart. What I have: ``` 1) Fresh AWS instance with Ubuntu 16.04 (t2.large: 2 cores, 8Gb RAM) 2) It has internal (10.10.10.100) and external IP addresses 3) It has DNS domain name (like gluu.somedomain.com) ``` How to reproduce: 1) Run this command: ``` apt-get update && apt-get upgrade -y ``` 2) add in the and of the file /etc/security/limits.conf: ``` soft nofile 65536 hard nofile 262144 ``` 3) Add the following line to /etc/pam.d/login: ``` session required pam_limits.so ``` 4) Value in /proc/sys/fs/file-max is greater then 65535 5) Run this commands: ``` echo "deb https://repo.gluu.org/ubuntu/ xenial main" > /etc/apt/sources.list.d/gluu-repo.list curl https://repo.gluu.org/ubuntu/gluu-apt.key | apt-key add - apt-get update apt-get install gluu-server-3.0.1 service gluu-server-3.0.1 start service gluu-server-3.0.1 login cd /install/community-edition-setup ./setup.py ``` 6) During installation: ``` Enter IP Address [10.10.10.100] : Enter hostname [localhost] : gluu.somedomain.com Enter your city or locality : Zurich Enter your state or province two letter code : ZH Enter two letter Country Code : CH Enter Organization Name : Gluu Enter email address for support at your organization : a@b.cc Enter maximum RAM for applications in MB [3072] : 6144 Optional: enter password for oxTrust and LDAP superuser [hlE3vzf0hMdD] : <only letters and digits, 10 symbols> Install oxAuth OAuth2 Authorization Server?

You'll receive redirect to https://gluu.somedomain.com/identity/ and then 503 Service Unavailable This steps has been performed on 3 different instances (but on the same AMI: ami-a8d2d7ce - standard Ubuntu 16 image on AWS): t2.medium, t2.large and m4.xlarge Can someone help me?

>> 9) In some while try to follow https://gluu.somedomain.com. You'll receive redirect to https://gluu.somedomain.com/identity/ and then 503 Service Unavailable Can you please check if all services are running properly? Services means... oxauth, identity, httpd, idp and solserver.

Definitely they're not working. In start service script missing commands that start them. After "service gluu.... start" I have to write this command: ``` for i in identity idp oxauth oxauth-rp; do service $i restart; done ``` Only in this case all will work.

Could I ask you when this release is going to be published? Your application is quite good, but now it's really buggy - on Ubuntu 16.04 somehow RAM memory that app using getting out of the limits, to restart application (service) we have to execute additional commands (for research we spent more than 5 hours), sometimes after installation on new clean system it even doesn't want to start... According to all this we're searching for a similar solution, but more stable. That's why I'm asking about new release.

Could you send me the link to my email address?

I think I am gonna fire up a Amazon VM with your specifications and see what's up there. >> It would be really great if you'll share with me the link to new release - I would like to test it.

Did a quick test, I didn't have any issue installing Gluu Server. Used Amazon AWS Ubuntu 16.04 and deb package I shared before. Attaching the whole output below. However, after reboot... 'identity' piece is not starting. Attaching another output here. Created github [issue](https://github.com/GluuFederation/community-edition-setup/issues/305) as well.
