I have 2 rservers in serverfarm.
But all the client requests are going to only 1 rserver.Loadbalacning method used here is least connections.
checked the probes,sh serverfarm ,sh serverice POLICY class map nameof the class.
Everywhere I see the another rserver up and functional.
but when I do sh conn rserver 1 ,I dont see any connections
but for sh conn rserver2 ,I see all the client request been established.Please help me on this

Good morning,
First of all, I think you were not completely accurate on your description. It is true that the connection numbers are quite different between both servers, but both are receiving connections:
s0adcace01/production# sh serverfarm epmcubeservers
serverfarm : epmcubeservers, type: host
total rservers : 2
---------------------------------
----------connections-----------
real weight state current total failures
---+---------------------+------+------------+----------+----------+---------
rserver: s0adcretepmsql1
10.129.13.236:0 8 operational 297 11635352 34
rserver: s0adcretepmsql2
10.129.13.237:0 8 operational 30 17864159 144
With that said, this kind of uneven load distribution is most of the time caused by a combination of the load-balancing algorithm configured on the serverfarm and the stickiness method configured.
If you send me some details on your configuration, I'll have a deeper look
Regards
Daniel
