send message timeout

[刘建刚 <li...@zto.cn>]

Hi guys,
    Any suggestions for  send message and get TimoutException occasionally?

   I come up with some  TimeoutException for my rocketmq 4.1 cluster. It may happens at any time,  rocketmq  busy or not. This should be problems of the broker side,
  because  many producers for different topics have this problem at the same time.
  Exceptions for the producers are such as below:
2018-11-22  14:23:35 WARN rtTime--1 - invokeSync: wait response timeout exception, the channel[192.168.X.X:10911]
   2018-11-22 14:23:35 WARN rtTime--1 - sendKernelImpl exception, resend at once, InvokeID: -7824673395974642880, RT: 3000ms, Broker: MessageQueue [topic=broker-c, brokerName=broker-c, queueId=0]

The rocketmq cluster consists of 4 brokers, a ,b c and d. a and b is added into the cluster when the cluster startup. c and d was added in for scale out. So you can see more data in 
for a and b in below picture. 
For the TimeoutException, only exists in broker-c and broker-d, which have less data than broker-a and broker-b.  There are some differences for them.

1. broker-a and broker-b with redhat 6.8 , broker-c and broker-d with centos 7.4.
2. All topics have queues broker-a and broker-b, and some topics have queues in broker-a, broker-b, broker-c and broker-d. (because of some test topic, broker-a has more data in as below picture shows)
