    Description

      Build 6.5.0-4926

      Observed panic "invalid memory address or nil pointer dereference" in query.log file while running eventing performance test with n1ql query.
      Eventing code-

      function OnUpdate(doc, meta) {
      	var docId = meta.id;
      	var select_query = SELECT * FROM `bucket-1` USE KEYS[$docId];
      	for (var r of select_query) {
      	}
      	select_query.close()
      	var upsert_query = UPSERT INTO `eventing-bucket-1` (KEY, VALUE) VALUES ($docId, 'Hello World');
      	upsert_query.close();
      }
      

      Cluster configuration-

      172.23.96.16:kv,n1ql
      172.23.96.17:kv,n1ql
      172.23.96.20:kv,n1ql
      172.23.96.23:kv,n1ql
      172.23.97.177:eventing

      Note that this is not consistently reproducible and rerun of same test does not show this panic, also last weekly build 6.5.0-4908 does not show this panic.

      Job where we see panic- http://perf.jenkins.couchbase.com/job/themis/4557
