时间类产生OutOfMemory错误 [英] Time class generating OutOfMemory Error

问题描述

我正在使用Time类并创建20 tps的时间类，但出现了以下错误.

I am using the Time class and creating it of 20 tps, but I am getting below error.

 Exception in thread "pool-1-thread-9" java.lang.OutOfMemoryError: unable to create new native thread

代码:-

class SheduleInMemRemove{
            Timer timer;
        Config cfg;
          String key;

           public SheduleInMemRemove(String key,int seconds,Config cfg,String MSG,String IP,String PORT,boolean isResponse)
           {
                this.key=key;
                this.cfg=cfg;
                 LoggerWR.logger.info("[IN URL] [inside SheduleInMemRemove constructor][going to sleep to IN memory key["+key+"] [wake up after "+seconds+" seconds] [MSG]["+MSG+"] [isResponse]["+isResponse+"]");
                cfg.addInMem(key,IP,PORT,MSG,isResponse);
                //LoggerWR.logger.info("[IN URL] [Going to shedule]");
                timer = new Timer();
                timer.schedule(new WakeUpInTask(),seconds*1000);
                //LoggerWR.logger.info("[IN URL] [Done]");
           }
                class WakeUpInTask extends TimerTask
                {
                public void run() {
                //System.out.format("Time's up!%n");
                LoggerWR.logger.info("[IN URL] [Inside the SheduleInMemRemove class going to remove the key]["+key+"] ["+cfg.removeInMem(key)+"]");
                 //cfg.removeInMem(key);
                    timer.cancel(); //Terminate the timer thread
                }
        }
    }

请帮助

推荐答案

每个新线程都将需要大量内存才能用于其调用堆栈.显然，您启动的线程多于内存.

Each new thread is going to require a big chunk of memory to use for its call stack. Apparently, you're launching more threads than you have memory for.

如果要创建大量计时器，则应考虑使用

If you're creating a large number of timers, you should consider using a ScheduledExecutorService instead.
