ZhangShenao opened a new issue #700: Potential Concurrent Risk in RouteInfoManager URL: https://github.com/apache/rocketmq/issues/700 The method scanNotActiveBroker() in RouteInfoManager : `public void scanNotActiveBroker() { Iterator<Entry<String, BrokerLiveInfo>> it = this.brokerLiveTable.entrySet().iterator(); while (it.hasNext()) { Entry<String, BrokerLiveInfo> next = it.next(); long last = next.getValue().getLastUpdateTimestamp(); if ((last + BROKER_CHANNEL_EXPIRED_TIME) < System.currentTimeMillis()) { RemotingUtil.closeChannel(next.getValue().getChannel()); it.remove(); log.warn("The broker channel expired, {} {}ms", next.getKey(), BROKER_CHANNEL_EXPIRED_TIME); this.onChannelDestroy(next.getKey(), next.getValue().getChannel()); } } }` Is there any Concurrent Risk when it.remove() without lock?
