Load balancing and Logging questions

Hello all,

I've 2 RMI servers fronted by haproxy 1.4.8, here is the config file:

global

        stats socket /tmp/stats
        pidfile /var/run/haproxy.pid
        daemon
defaults
        mode tcp
        option dontlognull retries 3 option redispatch
        maxconn 2000
        contimeout 5000
        clitimeout 50000
        srvtimeout 50000
listen  RMI 10.80.0.55:1099
        mode tcp
        balance roundrobin
        server dev103 10.80.0.206:1099
        server dev105 10.80.0.212:1099
listen  OTHER 10.80.0.55:10999
        mode http
        stats enable
        stats uri     /admin?stats

I've created a RMI client against the haproxy machine, and invoking functionS indeed directed to the concrete servers. The problem is, that after the client created, all traffic directed to only one server, and no load balance occures. Re-creating the client may result with traffic directed to the other server, but still - only to that server.

Question No. 1: Is my config file wrong?

I'm trying to figure it what I'm doing wrong, since my config file looks quite simple.

Question No. 2: Is there a way to configure haproxy to dump data regarding the traffic it directs to a simple file rarther than syslog server ? Trying to run with -d displayed some lines which do not tell me alot:

Available polling systems :

     sepoll : pref=400,  test result OK
      epoll : pref=300,  test result OK
       poll : pref=200,  test result OK
     select : pref=150,  test result OK

Total: 4 (4 usable), will use sepoll.
Using sepoll() as the polling mechanism.

00000000:RMI.accept(0004)=0007 from [172.16.0.190:4700]
00000000:RMI.srvcls[0007:0008]
00000000:RMI.clicls[0007:0008]
00000000:RMI.closed[0007:0008]
