+ * @file bug658.cpp regression case for bug 658 ("readconnroute: client is not closed if backend fails")
+ *
+ * - Connect all MaxScale
+ * - block Mariadb server on Master node by Firewall
+ * - execute query
+ * - unblock Mariadb server
+ * - do same test, but block all backend nodes
+ * - check if Maxscale is alive

+Reproduce:
+1. connect readconnroute with mysql client
+2. fail the backend server
+3. execute query by using mysql client
+
+>> client hangs if write to backend socket doesn't return error (which doesn't happen in many cases)
+Comment 1 Markus Mäkelä 2014-12-23 09:19:17 UTC
+Added a check for server status before routing the query. Now if the server is down it returns an error.
