• What is the cause and solution for SAP error message ESH_QL_MSG012 - Query log aggregation already running, process is locked ?

  The SAP error message ESH_QL_MSG012 indicates that a query log aggregation process is already running, and as a result, the system has locked the process to prevent concurrent executions. This is a common issue in systems where query log aggregation is scheduled to run periodically, and it can occur if a previous aggregation process has not completed before a new one is triggered.
  
  Cause:
  
  Concurrent Execution: The most common cause is that the query log aggregation job is scheduled to run at intervals that overlap, leading to multiple instances trying to run simultaneously.
  Long-Running Processes: If the previous aggregation process takes longer than expected due to a large volume of data or system performance issues, it can lead to this error.
  System Locking Mechanism: SAP uses locking mechanisms to ensure data integrity, and if a process is still running, it will prevent another instance from starting.
