It appears that you're encountering an issue related to server resource allocation. The error message suggests that one or more users on the server have exceeded their allocated memory (PMEM) limit.

To address this issue, you can follow these steps:

1. Identify the Affected User(s): Determine which user(s) on the server are causing the low PMEM limit. This information is crucial for troubleshooting.

2. Check Resource Usage:

   • Use system monitoring tools like top, htop, or server management panels (if available) to monitor resource usage in real time.
   • Pay attention to the memory usage of individual processes and users.

3. Adjust Resource Limits:

   • If you have the necessary permissions, consider increasing the PMEM limit for the affected user(s) using the server's control panel or command-line tools. This may involve modifying user-level resource limits or assigning additional resources to their account.

4. Optimize Resource Usage:

   • Encourage users to optimize their applications and code to use memory efficiently. This might involve optimizing database queries, reducing unnecessary resource-intensive processes, or using caching mechanisms.

5. Implement Resource Monitoring:

   • Implement ongoing monitoring of resource usage to catch any spikes or patterns of high usage early on. Automated monitoring tools or scripts can help with this.

6. Educate Users:

   • Educate users on best practices for resource management. Provide guidelines on how to optimize their applications for performance and efficiency.

7. Consider Isolating Users:

   • Depending on your server setup, consider isolating resource usage for different users or accounts to prevent one user from affecting others.

8. Implement Quotas:

   • Set user-specific resource quotas to ensure that no single user can consume an excessive amount of resources.

9. Regularly Review and Adjust:

   • Periodically review resource usage patterns and adjust allocations as needed. This helps ensure fair and efficient resource distribution.

10. Consider Upgrading Hardware:

    • If the server consistently struggles with resource limitations, consider upgrading the hardware to provide more resources for all users.

Remember to communicate any changes or actions taken to the affected users to ensure transparency and cooperation.

Please note that the exact steps and commands may vary depending on the specific server setup and control panel you're using. If you're not familiar with server administration, it might be a good idea to consult with a system administrator or IT professional for assistance.
