# decription:   
#                  Original ticket title: "Lost connexion with Big request"
#                  Test checks that:
#                  1) we *can* run query with <N> unions, where <N> is limit specific for 2.5.x vs 3.x
#                  2) we can *not* run query with <N+1> unions.
#                  Actual value of <N> is 128 for 2.5.x (NOT 255 as errormessage issues!) and 255 for 3.0.
#               
#                  Checked on WI-V2.5.7.27025, WI-V3.0.1.32598.
