    2. Check for Long-Running Transactions: Review the transactions that are currently running and see if any are taking longer than expected. If so, investigate why they are taking so long and optimize them if possible.
    3. Review System Logs: Check the system logs (transaction SM21) for any related error messages or warnings that might provide more context about the issue.
    4. Restart the Transaction: Sometimes, simply restarting the transaction that caused the error can resolve the issue.
