[GitHub] [rocketmq] dongeforever commented on pull request #2487: [ISSUE #2476] Fix HaClient Infinite loop

   @crazywen  The original reason is that the HAClient.READ_MAX_BUFFER_SIZE muse be equal or larger than the haTransferBatchSize.
   
   Otherwise, the slave HAClient cannot read all the data to byteBufferRead as it has been full already, and the reallocation will take no effect, the new buffer will still be full.
