This seems to be another symptom of the problem related to
es_query_dsa for which Thomas has sent a patch on a different thread
[1]. After applying that patch, I am not able to see the problem. I
think due to the wrong usage of dsa across nodes, it can lead to
sending some wrong values for params to workers.
