SVMCRT_SESSION_MGM020
- Session <&1> was probably loaded at same time by more than one VM ?The SAP error message SVMCRT_SESSION_MGM020 indicates that a session (identified by
<&1>
) was likely loaded simultaneously by more than one Virtual Machine (VM). This situation can lead to conflicts and inconsistencies in session management, as multiple VMs attempt to access or modify the same session data concurrently.Cause:
- Concurrent Access: The primary cause of this error is that multiple instances of the application or multiple VMs are trying to access the same session data at the same time. This can happen in environments where load balancing is used, and multiple application servers are running.
- Session Management Issues: There may be issues with how sessions are managed within the application, leading to improper handling of session states.
- Configuration Issues: Misconfiguration in the application server or session management settings can also lead to this error.
Solution:
- Review Session Management Configuration: Check the configuration settings for session management in your SAP environment. Ensure that sessions are being managed correctly and that there are no misconfigurations that could lead to concurrent access.
- Implement Locking Mechanisms: If possible, implement locking mechanisms to prevent multiple VMs from accessing the same session simultaneously. This can help ensure that only one VM can load or modify a session at a time.
- Load Balancer Configuration: If you are using a load balancer, ensure that it is configured correctly to route requests to the appropriate VM without causing session conflicts.
- Session Timeout Settings: Review and adjust session timeout settings to ensure that sessions are not held longer than necessary, which can help reduce the chances of concurrent access.
- Monitor and Analyze Logs: Check the application and system logs for any additional error messages or warnings that could provide more context about the issue. This can help identify patterns or specific scenarios that lead to the error.
- Update and Patch: Ensure that your SAP system is up to date with the latest patches and updates, as newer versions may contain fixes for known issues related to session management.
