+I found using basic routing hints such as:
+
+ select @@server_id; -- maxscale route to server server4
+ select @@server_id; -- maxscale route to server server3
+ select @@server_id; -- maxscale route to server server2
+
+server3 is the current master
+
+and server4 server_id is 4
+server3 server_id is 3
+server2 server_id is 2
+
+sometimes I cannot get the expected results that are:
+
+4
+3
+2
+
+
+Sometimes I got:
+
+2
+3
+2
+
+or
+
+4
+3
+4
+
+In maxScale configuration 5 servers defined:
+
+server1 is not monitored but listed in [RW Split Service]
+server5 is always stopped
+
+
+
+MaxScale configuration:
+
+[gateway]
+threads=4
+
+[RW Split Service]
+#Please note server1 is not monitored n MySQL Monitor section
+type=service
+router=readwritesplit
+servers=server1,server2,server3,server5,server4
+max_slave_connections=100%
+max_slave_replication_lag=21

+passwd=massi

+[RW Split Listener]
+type=listener

+servers=server4,server2,server3,server5
+user=massi
+passwd=massi
+detect_replication_lag=1
+monitor_interval=10001
+
+
+
+Removing server1 from the service section gives right results for server_id selection

+After further consideration we decided that the behavior is invalid. Routing hints should be followed if they don't violate database consistency nor cluster setup.
+Comment 11 Vilho Raatikka 2014-08-08 17:26:25 UTC
+Pushed fix in commit d4de582e1622908cc95396f57878f8691289c35b to Z2.
+Replication lag is not checked if routing hint is used.
