Have you ever gone on vacation only to come back and realize that you cannot access your Oracle Exalytics machine anymore? Your ILOM (Integrated Lights Out Manager) shows that system is up and your network team says that ports are open in the firewall…but it isn’t working?
It turns out that there is a bug in the system where the Oracle Exalytics Linux operating system may crash or become unresponsive after 208 continuous days of use.
To fix the issue you will have to restart your system. You can also refer to the following document on Oracle Support if you run into this issue: “Oracle Exalytics Stability and Performance Issues on Compute Nodes Running Linux After Uptime of More Than 208 Days (Doc ID 1579194.1).”
For your reference, the Oracle documentation states, “To avoid further occurrences of the 208 days issue; it is recommended that you pro-actively plan to reboot the server before 208 days of continuous up-time has been reached. By doing this, you will avoid any unplanned server outages.”
If you want permanently fix this issue, you’ll need to apply Patch Set 4 (PS4).
