My Ubuntu VM Keeps Freezing – Need Troubleshooting Tips!

Start by examining the last syslogs or journal entries right before the VM freezes. If this issue occurs frequently, your logs should show multiple instances. Look for patterns, like whether the VM boot time correlates with other events. Also, check if there are any resource usage metrics from your hosting provider that could indicate memory spikes or other usage issues. Keep an eye on logs for any specific times or events related to the problem. Good luck!

Make sure you have enough disk space and RAM available. I faced a similar issue where my VM was freezing because it was running out of swap space.

Thanks for the suggestions! I noticed that backup scripts still execute even when the server is unreachable, and logs indicate failed connections to the DB server and AWS. This leads me to believe it's more of a network issue rather than freezing. Any ideas on what might cause the loss of inbound and outbound traffic?

When diagnosing physical machines, think about what you'd check: analyze events leading up to the responsiveness loss. Have you tested SSH, ping, or application traffic? What about monitoring scheduled data streams? Also, is the console accessible, and are there any messages during the freeze? Check how often "every now and then" occurs and what metrics indicate before the issue happens. Review logs for any meaningful messages as well.
