title: kafka connect Skipping fetch for partition
body: <p>I have standalone confluent server that worked fine  until suddenly connect stooped to consume records .</p>
  
  <p>I enabled  trace on connect and this is the debug output .</p>
  
  <p><code>DEBUG Added READ_UNCOMMITTED fetch request for partition connect-offsets-10 at offset 0 to node 10.1.*.*:9092 (id: 1001 rack: null) (org.apache.kafka.clients.consumer.internals.Fetcher:787)</code> </p>
  
  <p>I did some research and found out that it`s can be  related to <a href="https://cwiki.apache.org/confluence/display/KAFKA/KIP-62%3A+Allow+consumer+to+send+heartbeats+from+a+background+thread" rel="nofollow noreferrer">KIP-62</a>.</p>
  
  <p>I try to reconfigure server proporties with those values but i got same result. </p>
  
  <pre><code>group.initial.rebalance.delay.ms=0
  session.timeout.ms=10000
  heartbeat.interval.ms=3000
  </code></pre>
  
  <p>Now the connect service is in deadlock state and unable to consume records.</p>
