body: <p>when filebeat output data to kafka , there are many warning message in filebeat log.</p>
  
  <p>..</p>
  
  <pre><code>*WARN producer/broker/0 maximum request accumulated, waiting for space
  
  *WARN producer/broker/0 maximum request accumulated, waiting for space
  </code></pre>
  
  <p>..</p>
  
  <p>nothing special in my filebeat config:</p>
  
  <p>..</p>
  
  <pre><code>output.kafka:
  
    hosts: ["localhost:9092"]
  
    topic: "log-oneday"
  </code></pre>
  
  <p>..</p>
  
  <p>i have also updated these socket setting in kafka:</p>
  
  <p>...</p>
  
  <pre><code>socket.send.buffer.bytes=10240000
  
  socket.receive.buffer.bytes=10240000
  
  socket.request.max.bytes=1048576000
  
  queued.max.requests=1000
  </code></pre>
  
  <p>...</p>
  
  <p>but it did not work. </p>
  
  <p>is there something i missing? or i have to increase those number bigger?</p>
  
  <p>besides , no error or exception found in kafka server log</p>
  
  <p>is there any expert have any idea about this ? </p>
