Queries that were dropped because the request list was full.
This happens if a flood of queries need recursive processing, and the
server can not keep up.
+The counter is increased when during the flood there is no space
+to be made with the jostle out of an older query, and the new query
+is dropped.
+Since no older queries are removed, see
+\fI\%jostle\-timeout\fP setting, there
+is no space for the new query.
