SAP S/4HANA Error 5150: Text Stream Conflict
Description
Error 5150, 'ERR_TEXT_COMMON_STREAM_ALREADY_OPEN', indicates that a program or process attempted to open or access a data stream (e.g., for text, files, or data transfer) that is already active and in use. This typically occurs when a resource is not properly released by a previous operation, or when concurrent processes try to access the same stream.
Error Message
ERR_TEXT_COMMON_STREAM_ALREADY_OPEN
Known Causes
3 known causesConcurrent Stream Access
Multiple processes, user sessions, or background jobs are attempting to access or modify the same data stream simultaneously.
Improper Stream Closure
A previous operation or program execution failed to properly release or close the data stream, leaving it in an 'open' state.
Application Logic Error
An issue within custom application code or a standard SAP process is attempting to re-open an already active data stream unnecessarily.
Solutions
3 solutions available1. Restart SAP Application Server Instance easy
A simple restart can clear temporary resource locks causing the text stream conflict.
1
Log in to the SAP system's operating system as a user with administrative privileges.
2
Navigate to the SAP instance's control directory. Typically, this is located in the SAP system's installation path, e.g., `/usr/sap/<SID>/<InstanceName>/work/` or `C:\Program Files\SAP\<SID>\<InstanceName>\work\`.
3
Execute the stop script for the application server instance. This is usually `stopsap` (Linux/Unix) or `stopsap.bat` (Windows).
4
Wait for the instance to completely stop. Monitor the processes to ensure they have terminated.
5
Execute the start script for the application server instance. This is usually `startsap` (Linux/Unix) or `startsap.bat` (Windows).
6
Verify that the SAP instance has started successfully and that the error 5150 is no longer occurring.
2. Identify and Terminate Conflicting SAP Work Processes medium
This solution involves pinpointing and stopping specific work processes that might be holding the text stream resource.
1
Log in to the SAP GUI and access transaction SM50 (Work Process Overview) or SM66 (Global Work Process Overview).
2
Observe the list of work processes. Look for any processes that are in a 'running' state and might be related to text processing or I/O operations, especially if the error occurred during a specific transaction or background job.
3
If a suspicious work process is identified, note its Process ID (PID).
4
As a system administrator, log in to the operating system of the SAP application server where the identified work process is running.
5
Use the operating system's process management tools to terminate the process using its PID. For Linux/Unix, this would be `kill -9 <PID>`. For Windows, use Task Manager or `taskkill /F /PID <PID>`.
6
After terminating the process, try to re-run the operation that caused the error to see if it is resolved.
7
If the issue persists, consider restarting the affected SAP application server instance as a more comprehensive approach (refer to 'Restart SAP Application Server Instance').
3. Analyze SAP Trace Files for Detailed Error Context advanced
Deep dive into trace files to understand the exact sequence of events leading to the text stream conflict.
1
Identify the time frame when the error 5150 occurred.
2
Access the SAP system's trace directories. Common locations include `/usr/sap/<SID>/<InstanceName>/work/` (Linux/Unix) or `C:\Program Files\SAP\<SID>\<InstanceName>\work\` (Windows).
3
Examine the developer traces (`dev_w*` files) for the work processes that were active around the time of the error. Look for entries related to 'ERR_TEXT_COMMON_STREAM_ALREADY_OPEN' or any other I/O or file handling errors.
4
If available and enabled, check the system trace (`trc_w*` files) for more granular information on system calls and resource usage.
5
Look for any specific function modules or program names mentioned in the trace files that were being executed. This can help identify the source of the conflict.
6
If the traces point to a specific SAP Note or known issue, consult SAP Support Portal for relevant patches or solutions.
7
If the cause remains unclear, consider increasing the trace level for relevant components (e.g., using transaction ST05 for SQL tracing or ST01 for system call tracing) and reproducing the error to gather more detailed information.
