    Description

      The code introduced as part of following commits can cause projector to panic due to race condition on feed cleanup.

      https://github.com/couchbase/indexing/commit/2e56e3d535dfaeb1b2615eca822f42c28e502e2d
      https://github.com/couchbase/indexing/commit/c21d01188a5509208d89257af7fc578e45c12796

      During cleanup, the genServer sets feed.conn=nil, while the doReceive can still try to access this.

      As the above commits were backported to 5.5.4 and 6.0.1, the fix will also need to be backported.
