• What is the cause and solution for SAP error message PS4S009 - No free server resources available ?

  The SAP error message PS4S009: No free server resources available typically indicates that the SAP system is unable to allocate the necessary resources to process a request. This can occur for various reasons, including:
  Causes:
  
  Resource Exhaustion: The SAP application server may have reached its limit for available resources, such as memory, CPU, or user sessions.
  Configuration Limits: The system may be configured with limits on the number of concurrent users or sessions, which can lead to resource unavailability.
  Long-Running Processes: Background jobs or long-running transactions may be consuming resources, preventing new requests from being processed.
  Network Issues: Problems with network connectivity can also lead to perceived resource unavailability.
  Database Locks: If the database is locked or busy, it may not be able to allocate resources to the SAP application server.
  
  Solutions:
  
  Check System Load: Monitor the system's performance metrics (CPU, memory, and user sessions) using transaction codes like SM50 (for process overview) and SM66 (for global process overview).
  Increase Resource Limits: If the system is consistently hitting resource limits, consider increasing the configuration limits for user sessions or memory allocation.
  Terminate Long-Running Processes: Identify and terminate any long-running or stuck processes that may be consuming resources unnecessarily.
  Review Background Jobs: Use transaction SM37 to check for background jobs that may be running longer than expected and consuming resources.
  Check for Locks: Use transaction SM12 to check for database locks that may be preventing resource allocation.
  Restart Application Server: In some cases, restarting the application server can help free up resources.
  Consult Basis Team: If the issue persists, consult your SAP Basis team for further analysis and potential adjustments to system parameters.
