# title:        Bugcheck 167 (invalid SEND request)
# decription:   
#                    Reproduced on: WI-V3.0.1.32609 - got in firebird.log:
#                        "internal Firebird consistency check (invalid SEND request (167), file: JrdStatement.cpp line: 325)"
#                    On client side got:
#                        DatabaseError:
#                        Error while rolling back transaction:
#                        - SQLCODE: -902
#                        - internal Firebird consistency check (can't continue after bugcheck)
#                        -902
#                        335544333
#               
#                    Test extracts content of firebird.log, then runs scenario which earlier led to "invalid SEND request (167)"
#                    and then again get firebird.log for comparing with its previous content.
#                    The only new record in firebird.log must be:
#                        "Modifying procedure SP_CALC_VAL which is currently in use by active user requests"
#                    Checked on:
