To address the issue of the Apollo portal crashing after running for a period of time, consider the following recommended practices to prevent such crashes:

1. Namespace and Configuration Item Limits:

   • Enable and configure limits on the number of namespaces and configuration items to prevent resource exhaustion. This can be done by setting namespace.num.limit.enabled and item.num.limit.enabled to true, and adjusting namespace.num.limit and item.num.limit accordingly ^[1][2].

2. Cluster Management:

   • Ensure cluster names are consistent with IDC attributes in the server.properties file. This helps maintain a clear cluster structure and prevents misconfigurations ^[1][2].

3. Security and Permissions:

   • Implement authentication and fine-grained permissions to control access and prevent unauthorized changes that could lead to instability ^[1][2].

4. Release Audits:

   • Enable release audits in production environments to ensure configuration changes are reviewed before being applied ^[1][2].

These practices help manage resources effectively and maintain application stability. If the issue persists, reviewing the logs for specific error messages or exceptions related to Tomcat, Hibernate, or Spring components could provide further insights into the cause of the crashes.
