title: how to fix fluentd(td-agent) buffer problem?
body: <p>I have an fluentd, elasticsearch, graylog setup and I'm getting below error intermittently in td-agent log</p>
  
  <blockquote>
    <p>[warn]: temporarily failed to flush the buffer. next_retry=2019-01-27
    19:00:14 -0500 error_class="ArgumentError" error="Data too big (189382
    bytes), would create more than 128 chunks!"
    plugin_id="object:3fee25617fbc"</p>
  </blockquote>
  
  <p>Because of this cache memory increases and td-agent fails to send messages to graylog</p>
  
  <p>I have tried setting the buffer_chunk_limit to 8m and flush_interval time to 5sec</p>
