+ * @file bug495.cpp regression case for bug 495 ( Referring to a nonexisting server in servers=... doesn't even raise a warning )
+ *
+ * - Maxscale.cnf with "servers= server1, server2,server3  ,server4,server5"
+ * but 'server5' is not defined. Test checks error log for proper error message.
+ * - check if Maxscale is alive

+Description Hartmut Holzgraefe 2014-08-31 21:32:09 UTC
+Only [server1] and [server2] are defined,
+service [test_service] and monitor [MySQL monitor]
+refer to a third server "server3" in their servers=...
+list though ...
+
+Nothing in the err or msg log hints towards a problem ...
+(which originally was caused by a copy/paste error that
+also lead to the "duplicate section name" error reported
+earlier ... and which would have been easy to track down
+if either of these problems would at least have raised a
+warning - took me almost an hour to track down the actual
+problem ... :(
