SAP S/4HANA Error 5346: LxP Resource Initialization Failure
Description
Error 5346 indicates a failure during the initialization of an LxP (Learning Experience Platform) resource within SAP S/4HANA. This typically occurs when the system attempts to load or configure components related to user experience, guided learning, or contextual help, preventing proper display or functionality.
Error Message
ERR_TEXT_LA_LXP_RES_INIT_4
Known Causes
4 known causesIncorrect LxP Configuration
The LxP resource might be misconfigured in the SAP S/4HANA system, leading to initialization failures.
Missing or Corrupt Resources
Essential files or data required for the LxP resource to initialize correctly may be missing or have become corrupted.
Network Connectivity Issues
Problems with network connectivity to external LxP services or internal SAP components can prevent resource initialization.
Insufficient User Permissions
The user attempting to access or initialize the LxP resource may lack the necessary authorizations.
Solutions
4 solutions available1. Restart SAP Application Server Instances easy
A simple restart often resolves transient resource initialization issues.
1
Log in to the SAP system using an administrator user (e.g., SAP*, DDIC).
2
Open transaction SM51 to view the application server instances.
3
Select all running instances and choose 'Server' -> 'Restart' from the menu.
4
Monitor the instance status in SM51 until they are all running again. Verify if the error 5346 is resolved.
2. Verify and Adjust Kernel Parameters medium
Incorrect or insufficient kernel parameters can lead to resource initialization failures.
1
Log in to the SAP system using an administrator user.
2
Open transaction RZ10 and load the instance profile.
3
Search for parameters related to shared memory, process management, and network buffers. Common parameters to check include:
ztta/roll_area
ztta/shm_area
SHM_MAX_SIZE
SHM_SEGMENTS
Gw_max_conn
Gw_max_sys_conn4
Consult SAP Notes relevant to error 5346 and your specific S/4HANA version for recommended parameter values. For instance, ensure sufficient memory is allocated for roll areas and shared memory segments.
5
If modifications are made, save the profile and restart the SAP application server instances (as described in Solution 1).
3. Check Operating System Resources and Limits medium
The underlying operating system might be lacking resources or have restrictive limits.
1
Log in to the operating system of the SAP application server.
2
Check system logs for any OS-level errors related to memory, disk space, or process creation. For Linux/Unix, use commands like `dmesg`, `syslog`, or `/var/log/messages`.
dmesg | tail -n 50
cat /var/log/messages | tail -n 1003
Verify available disk space in the directories used by SAP (e.g., `/usr/sap/<SIDs>/<instance>/work`, `/usr/sap/<SIDs>/<instance>/log`).
df -h4
Review OS limits for the SAP user (e.g., `nofile`, `nproc`, `memlock`). On Linux/Unix, these are often configured in `/etc/security/limits.conf` or files within `/etc/security/limits.d/`.
ulimit -a5
If OS resource constraints are found, work with your OS administrator to increase limits or free up resources. After making OS changes, restart the SAP application server instances.
4. Analyze SAP Trace Files for Deeper Issues advanced
Detailed trace files can pinpoint the exact cause of the LxP resource initialization failure.
1
Log in to the SAP system.
2
Open transaction ST11 and select the 'Trace' directory. Look for trace files generated around the time of the error 5346.
3
Focus on trace files like `dev_w*` (work process traces) and `gwrd_*.trc` (gateway traces).
4
Examine the trace files for specific error messages, memory dumps, or indications of resource exhaustion (e.g., failures to allocate shared memory, network communication issues).
5
Search SAP Notes using keywords from the trace file errors. If the issue is complex or related to internal SAP behavior, you may need to open a support incident with SAP and provide these trace files.
