Couple of days back I created an instance in AWS with CentOS - MySQL - R - Shiny-Server. The shiny-server is a free version. I loaded my app, data into MySQL. My app ran without a glitche for two days. Since yesterday afternoon, I am getting a "Failed to connect: message" from Safari. When I explored I figured out why shiny-server got stopped, I got the following message:
systemctl status shiny-server -l
● shiny-server.service - ShinyServer

When i checked the /var/log/shiny-server.log i am getting the following error.
^[[32m[2016-06-29 02:51:03.902] [INFO] shiny-server - ^[[39mShiny Server v1.4.2.786 (Node.js v0.10.40)

When I removed the comment on the PIDfile line got the following error:
Job for shiny-server.service failed because a configured resource limit was exceeded.
Going by examples here at SO i tried doing the following:
Commented out the line PIDfile=/var/run/shiny-server.pid and changed the Type=forking from simple in the /etc/systemd/system/shiny-server.service file. Stop, start, restart shiny-server with commenting out, commenting in the pid file didn't seem to work.
Tried adding a link ln -s shiny-server.service /systemd/system/multi-user.target.wants but got a message file already exits. Not sure how to start the server again.
