503 Service Unavailable error Apache Tomcat

I try to deploy my Java project Apache Tomcat server but sometimes it gets down and returns me this page

service unavailable 503

Tomcat is installed on the Digitalocean's Ubuntu 14.04 and droplet's properties are 512Mb/1CPU, 20GB SSD Disk, 1000 GB transfer. I took the lowest option for test purposes. The site is visited by nobody except me and from the graphs I observe that the server is not overloaded at all. Most of the time everything works fine until suddenly the server returns 503. After I restart it keeps working fine again till the next 503 error in several days. I'd like to know what could cause this error: my mistake on configuring the server or maybe problems on server side?

You arn't giving any information that can be used to debug this. Have you looked around at the apache and the tomcat logs ? - nos

That mean tomcat is not running. You can use the alias command to up the tomcat service or just go in the current directory and start the service.

Example: # tomcatup /opt/tomcat8/bin/startup.sh
