body: <p>I'm trying to insert bulk data into Neo4j using a script. After a while the script breaks with the following Exception.</p>

  <p>The same query works from console and restarting the script from the same point where exception occurred works again for a while until it fails again. Catching the Exception and making the script sleep for few seconds does not break the script.</p>
  
  <p>Any suggestions on what might be happening here?</p>
  
  <p>UPDATE: Added a sample query</p>
  
  <pre><code>START a = node:?("?:?"), b = node:?("?:?")
              MATCH a-[c1:ACTIVITY_LIST*]-&gt;z, z-[r1:ACTIVITY_LIST]-&gt;y
              WHERE z.TIMESTAMP &gt;= '.$time.' AND y.TIMESTAMP &lt; '.$time.'
              CREATE n = {?}, clist = {COMMENT_ID: ''}, a-[:IN_?]-&gt;n, n-[:OUT_?]-&gt;b, n-[:COMMENT_LIST]-&gt;clist, z-[:ACTIVITY_LIST]-&gt;n, n-[:ACTIVITY_LIST]-&gt;y
              DELETE r1
              RETURN n;
