Some Warning happen When run a stategy that close all order at real market, as like that:
05:43:31 Strategy thread queue overloaded with tasks. Ticks in queue - 3, bars - 1612, other tasks - 417

The Strange is it don't happen at test market, but it happens all the time at real market operation.

Most likely there is some execution logic in your strategy, which prevents the onBar method to get called. To find out the exact cause of the problem, please provide:

1. An example strategy which replicates the case.
2. The launch conditions - essentially, the number of subscribed instruments.

My Stategy is close all order which I concern. The main code is recode onStart function as follows:

public void onStart(IContext context) throws JFException {
        this.engine = context.getEngine();
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.context = context;
        this.indicators = context.getIndicators();
        this.userInterface = context.getUserInterface();
        
        if (JOptionPane.showConfirmDialog(null, "Close All BUY and SELL","Close", JOptionPane.YES_NO_OPTION) != JOptionPane.YES_OPTION){
            // 停止执行策略
            context.stop();
            return;
        }
        
        double slippage = 2;
        java.util.List<IOrder> orderList = engine.getOrders();
        for (IOrder order : orderList) {    // 循环遍历orderList
            if (order != null){
                // 只有本策略有权限管理的订单才能管理
                if (!isStrategyManage(order.getLabel()))
                {
                    continue;
                }

                // 订单全部平仓
                order.close();
            }
        }
        
        // 停止执行策略
        context.stop();
    }

By the way, The launch conditions is run the stategy at real market.

the stategy is meant to close more than 6 trades at once.

If the dialog remained opened for a while, then it would explain the queueing up of the bars, as waiting on the confirmation holds on the strategy execution.
