How To Troubleshoot Random App Crashes on Ubuntu 22.04

Ubuntu 14

Ubuntu 22.04 is a robust and reliable operating system. However, like any other software, it can sometimes experience issues such as random application crashes. This article will guide you through the process of troubleshooting these issues.

Quick Answer

To troubleshoot random app crashes on Ubuntu 22.04, you can start by checking for issues with the systemd-oomd service using the journalctl -u systemd-oomd command. If this service is the cause, you can either disable it temporarily with systemctl disable --now systemd-oomd or increase your system’s swap size. If the issue persists, you can also check the systemd journals for other error logs or consider seeking further assistance.

Understanding the Problem

Random application crashes can occur due to various reasons including insufficient system resources, software bugs, or compatibility issues. One common cause is the systemd-oomd service, a userspace out-of-memory killer that closes applications when the system is low on swap space.

Checking for systemd-oomd Issues

To check if systemd-oomd is causing the crashes, open the Terminal and run the following command:

journalctl -u systemd-oomd

This command displays the logs for the systemd-oomd service. If you see logs indicating that systemd-oomd killed your applications, this service is likely the cause of the crashes.

Addressing systemd-oomd Issues

If systemd-oomd is causing the crashes, there are two primary solutions:

1. Disable systemd-oomd

You can disable systemd-oomd by running the following command:

systemctl disable --now systemd-oomd

This command stops the systemd-oomd service and prevents it from starting at boot. However, this change may not persist after a reboot, and it’s generally not recommended as it can lead to other issues.

2. Increase Swap Size

A better solution is to increase your system’s swap size. Insufficient swap space can lead to application crashes, especially on systems with limited RAM. You can follow this guide on how to increase swap size.

Checking for Other Issues

If the above solutions do not resolve the issue, you can check the systemd journals for any other error logs or crash reports. Run the following command:

journalctl

This command displays the system logs, which can provide valuable information about system errors and crashes.

Conclusion

Troubleshooting random application crashes on Ubuntu 22.04 involves understanding the potential causes, checking for issues with systemd-oomd, and increasing swap size if necessary. If these steps do not resolve the issue, you may need to seek further assistance or consider downgrading to a more stable version of Ubuntu. Remember, troubleshooting is a process of elimination. Be patient and persistent, and you’ll likely find a solution.
