ISSUE: 671
|
|
TITLE: Unsuccessful execution caused by system error <...> bad BLR -- invalid stream
|
|
DESCRIPTION:
|
|
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.
