connector using al memory (no replies)

For any reason the Query and the Result variables end up using all the system memory. How do I clear the Query and the Result variable, so I can continue using it

sql::Statement *Query;
sql::ResulSet *Result;
while(1){
Query = con->createStatement();
Result = Query->executeQuery("SELECT `Some` FROM `Table` LIMIT 1");
Result->next();
Result->close();
Query->close();
cout << "console message..." << endl;
}
