**BUG REPORT** 1. Please describe the issue you observed: ### 问题描述 生产者通过VIP通道发送消息，假如，每天发送100条，量不大。服务端有个AllIdleTimeoutTask任务，判断通道是否空闲，如果120秒没使用，就关闭了。主通道因为有心跳每30秒一次，刷新lastWriteTime值，所以主通道基本上不会关闭。但是vip通道没有心跳，所以如果发送量不大，超过时间就会关闭。 ### 疑问 假如生产者通过vip通道发送消息，请求过来了，但是还没来得及刷新lastWriteTime或者lastReadTime值，AllIdleTimeoutTask这个时候正好将通道关闭了。 客户端报错，超时。wait response on the channel <:10909> timeout, 10000(ms)。服务端日志正好是10秒之前有个closeChannel: close the connection to remote address。 2.
