• What is the cause and solution for SAP error message LDAPRC090 - Insufficient memory space ?

  The SAP error message LDAPRC090 Insufficient memory space typically indicates that the system has run out of memory resources while trying to perform an operation related to LDAP (Lightweight Directory Access Protocol). This can occur during various operations, such as user authentication or directory queries.
  Causes:
  
  Insufficient System Memory: The server may not have enough physical or virtual memory available to handle the LDAP operations.
  Configuration Issues: Incorrect configuration settings in the LDAP or SAP system can lead to excessive memory usage.
  High Load: A high number of concurrent LDAP requests can overwhelm the system's memory capacity.
  Memory Leaks: There may be a memory leak in the application or the LDAP server, causing memory to be consumed without being released.
  Large Data Sets: Attempting to process large datasets or complex queries can require more memory than is available.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Check the server's memory usage and consider increasing the physical or virtual memory allocated to the SAP system or the LDAP server.
  Adjust the SAP memory parameters in the instance profile (e.g., abap/heap_area_total, abap/heap_area_dia, etc.) to allocate more memory.
  
  
  
  Optimize LDAP Queries:
  
  Review and optimize the LDAP queries being executed to ensure they are efficient and not requesting more data than necessary.
  Limit the scope of queries or use filters to reduce the amount of data being processed.
  
  
  
  Monitor and Manage Load:
  
  Monitor the number of concurrent LDAP requests and manage the load on the server. Consider implementing load balancing if necessary.
  Schedule heavy LDAP operations during off-peak hours to reduce the load on the system.
  
  
  
  Check Configuration:
  
  Review the LDAP configuration settings in the SAP system to ensure they are set correctly and are not causing excessive memory usage.
  Ensure that the LDAP server is properly configured to handle the expected load.
  
  
  
  Update Software:
  
  Ensure that both the SAP system and the LDAP server are running the latest patches and updates, as these may contain fixes for memory-related issues.
  
  
  
  Restart Services:
  
  If the issue persists, consider restarting the SAP instance or the LDAP server to clear any temporary memory issues.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to LDAP and memory management.
  System Logs: Review system logs for additional error messages or warnings that may provide more context about the memory issue.
  Performance Monitoring Tools: Utilize performance monitoring tools to analyze memory usage patterns and identify potential bottlenecks.
  
  If the problem continues after trying these solutions, it may be necessary to engage SAP support or your system administrator for further investigation and assistance.
