SAP S/4HANA Error 5151: Stream Closed Transaction Failure
Description
This error indicates that an attempt was made to perform an operation or transaction using a data stream that has already been closed. It typically occurs when the connection or data channel unexpectedly terminates during a process, preventing further data exchange.
Error Message
ERR_TEXT_COMMON_STREAM_CLOSED
Known Causes
4 known causesNetwork Connectivity Loss
An unstable or interrupted network connection between the user, SAP S/4HANA, or an integrated system can prematurely close the data stream.
Session Timeout
A user session may have timed out due to inactivity, causing the underlying communication stream to close before a transaction is completed.
External System Disconnection
If SAP S/4HANA is communicating with an external system, that system might have disconnected or closed its data stream unexpectedly.
Server Resource Issues
Temporary server-side issues, such as resource exhaustion or an unexpected process termination, can lead to the abrupt closing of data streams.
Solutions
4 solutions available1. Restart SAP Application Server Instances easy
A quick restart of the relevant SAP application server instances can often resolve transient stream issues.
1
Identify the SAP application server instances that are experiencing the error. This might be indicated in the SAP system logs (SM21) or by specific user reports.
2
Access the SAP system administration interface (e.g., SAP GUI).
3
Navigate to transaction SM51 to view the work processes and instances.
4
Select the problematic application server instance(s).
5
Initiate a restart of the selected instance(s). This is typically done via the instance control menu (e.g., 'Instance' -> 'Restart'). Be aware that this will briefly interrupt user sessions on that instance.
6
Monitor the instances to ensure they come back up successfully and that the error no longer occurs.
2. Analyze and Adjust Network Connectivity medium
Investigate and potentially reconfigure network settings between SAP components or clients if network instability is suspected.
1
Check network connectivity between the SAP application servers and any external systems or databases involved in the transaction. This could include SAP HANA, other databases, or external services.
2
Use network diagnostic tools like `ping` and `traceroute` from the SAP application server to the target system to identify latency or packet loss.
ping <target_ip_address>
traceroute <target_ip_address>3
Review firewall configurations to ensure that the necessary ports for SAP communication are open and not being blocked. Consult with your network administration team.
4
Examine SAP Gateway configurations (transaction SMGW) for any signs of connection issues or timeouts.
5
If the error occurs during communication with SAP HANA, check the network configuration and connectivity between the SAP application servers and the HANA database nodes.
3. Investigate and Resolve Database Resource Constraints advanced
Ensure the SAP HANA database has sufficient resources and is not experiencing performance bottlenecks that could lead to stream closures.
1
Access the SAP HANA database monitoring tools (e.g., SAP HANA Cockpit or SQL Console).
2
Check for high CPU utilization, memory pressure, or disk I/O bottlenecks on the SAP HANA database server(s).
SELECT * FROM SYS.M_LOAD;
SELECT * FROM SYS_DATABASES.M_GLOBAL_VIRTUAL_MEMORY WHERE DATABASE_NAME = '<your_database_name>';3
Analyze the SAP HANA trace files for any errors or warnings related to network connections, timeouts, or resource exhaustion during the time the error occurred.
4
Review SAP HANA alert configurations and investigate any critical alerts that might indicate underlying resource issues.
5
If resource constraints are identified, consider scaling up the SAP HANA hardware (CPU, RAM, storage) or optimizing database queries and data models.
6
Ensure that SAP HANA system parameters related to network timeouts or connection pooling are appropriately configured and not too restrictive.
4. Review SAP System Logs for Underlying Causes medium
A deep dive into SAP system logs can reveal the specific context and root cause of the stream closure.
1
Access the SAP system logs using transaction SM21 (System Log).
2
Filter the logs by the time the error 5151 occurred. Look for other error messages or warnings that appeared around the same time.
3
Examine the details of the error 5151 message. It might contain specific information about the program, function module, or data stream involved.
4
Check the SAP application server's operating system logs (e.g., `/var/log/messages` on Linux) for any system-level errors that might have occurred concurrently.
5
If the error is related to a specific transaction or business process, try to reproduce the scenario and observe the logs in real-time.
6
Use the SAP Notes search functionality in SAP Support Portal with the error code and any relevant keywords found in the logs to find known issues and their resolutions.
