title: rds has a lot of messages Got an error reading communication packets
body: <p>I faced with errors in RDS mysql 5.7 logs:</p>
  
  <pre><code>[Note] Aborted connection 239056 to db: 'db' user: 'prod' host: '172.54.8.641' (Got an error reading communication packets)
  </code></pre>
  
  <p>I reade alot of articls but I'm not able fixed my issue yet. Now I create new "Parameter groups" for rds with values:</p>
  
  <pre><code>wait_timeout - 28800
  interactive_timeout - 28800
  connect_timeout - 28800
  max_allowed_packet - 1073741824
  net_read_timeout - 20
  net_write_timeout - 20
  </code></pre>
  
  <p>and absolutely nothing.
  I held meeting with developers and saw code when I made shure that connections was closed after finish.</p>
