It seems like you're encountering an issue with LVE (Lightweight Virtual Environment) where users with LVE enabled are reporting 100% RAM usage and invalid values in meminfo. This could be caused by a variety of factors. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Resource Limits:

   • Ensure that the resource limits for LVE users are set correctly. Verify that there are no excessively low limits that might be causing issues.

2. Check for Resource Overcommitment:

   • It's possible that the system is overcommitting memory, which can lead to inaccurate memory reporting. Check if overcommit is enabled and consider adjusting it if necessary.

3. Check for Memory Leaks:

   • Investigate if there are any processes or applications on the server that might be causing memory leaks. A runaway process could be consuming excessive memory.

4. Check for Misconfigured LVE Settings:

   • Review the LVE configuration to ensure that it's properly set up and that there are no conflicting settings.

5. Update LVE and Related Software:

   • Make sure you're using the latest version of LVE and any related software. There might be bug fixes or improvements in newer versions.

6. Check System Logs:

   • Examine system logs for any error messages or warnings related to LVE or memory usage. This can provide valuable clues about what might be going wrong.

7. Monitor Processes:

   • Use tools like top, htop, or other process monitoring tools to identify which processes are consuming the most memory.

8. Check for Swap Usage:

   • Check if your system is using swap space extensively. If it is, it might indicate that physical RAM is exhausted, which could be contributing to the issue.

9. Consider Hardware Limitations:

   • Ensure that your server hardware meets the requirements for the applications and services running on it. Inadequate hardware can lead to performance issues.

10. Contact Hosting Provider or Support:

    • If you're using a managed hosting service, contact your provider's support team. They may have specific insights or solutions for this issue.

11. Verify Memory Reporting:

    • Ensure that you're using reliable tools to monitor memory usage. Some third-party tools or scripts might report inaccurate information.

12. Test in a Controlled Environment:

    • If possible, replicate the issue in a controlled environment (like a test server) to see if you can isolate the problem.

Remember to take appropriate precautions and backups before making any significant changes to your server configuration. If you're not comfortable making these changes yourself, consider seeking the assistance of a system administrator or IT professional.
