Other threads are modifying Collection, either with a for implementation or a new List reserved deleted object, and then call List remove to delete the implementation

Yes,i do!

I tried to use the ProcessExplorer monitor thread to find that many idle threads had not been destroyed; 

How do you analyze the dump file? @caozhiyuan

我们的业务场景是在早晨、下午设备会打开，然而中午跟晚上很多都会关闭，在设备断线重连后资源监视器中的线程会增多，应该是原有的连接未释放，而我有加入ReadTimeoutHandler,Handler中有捕获相关异常； 关键代码如下 ` public void Init(ServerOptions options,Func handler) { _options = options; if (options.EventLoopCount > 0) { bossGroup = new MultithreadEventLoopGroup(options.EventLoopCount); } else { bossGroup = new MultithreadEventLoopGroup(); } workerGroup...

 应该是这里引起的异常，本机调试发现，这里开启了大量线程

Thank you，Get to a skill for windbg, I'll change HashedWheelTimer to a single case！

IByteBuffer imsg = (IByteBuffer)msg; byte[] result = new byte[imsg.ReadableBytes]; imsg.ReadBytes(result); When your data is greater than 1KB, you need to set bootstrap.ChildOption(ChannelOption.RcvbufAllocator,new AdaptiveRecvByteBufAllocator(64,1048,65536));

It's supposed to be my business code problem, thank you.
