I have been running Ubuntu server 14.04 for around two years. But sinds a few weeks the server crashes and burns each day. It is unclear to me why this is happening.
I checked log files in /var/log but these do not provide any information on why or even that the server is going down.
Is there is structured approach to troubleshooting these crashes? Can I increase loging somehow / somewhere?
Does it mean something anything there is no information indicating problems of some sort? This type of crash is similar to just turing power off maybe?
You might want to inspect the syslog if the logging suddenly stopped at some point then resumed showing signs of booting up. This might indicate a server crash due to hardware.
RAM issue is possible. We also encountered a similar problem with one of our servers overheating and suddenly powering off. I hope this helps.
