I've set up four **server** and **sentinel** instances on four different virtual machines in a simple master-slave setup.
The key replication works fine, and all redis nodes recognized each other (I'm referring to the `known-sentinel` and `known-slave` options).

The problem comes up when I'm trying to simulate a failure. The sentinels just keep telling that they can't elect a new master (**failover-abort-not-elected**):

    12481:X 22 Jun 17:20:05.761 # <__IP1__>:51002 voted for a3ba8d8cd0c15c8b186b44ba529b83d3a8424a42 27
    12481:X 22 Jun 17:20:14.140 # -sdown master mymaster <__IP2__> 6379
    12481:X 22 Jun 17:20:14.140 # -odown master mymaster <__IP2__> 6379
    12481:X 22 Jun 17:20:16.567 # -failover-abort-not-elected master mymaster <__IP2__> 6379

Another strange thing that when I query the sentinel's state in `redis-cli`, I keep getting greater values for the number of available sentinel instances than the actual count (which is of course, cannot be greater then 4 (right?)).

    $ redis-cli -p 51001
    > info
    [...]
    master0:name=mymaster,status=ok,address=91.120.59.231:6379,slaves=3,sentinels=8

Here's one of the sentinels' config:

    daemonize yes
    pidfile "/var/run/redis/redis-sentinel.pid"
    logfile "/var/log/redis/redis-sentinel.log"
    
    # bind 192.168.1.100 10.0.0.1
    # port 26379
    
    port 51004
    
    dir "/var/lib/redis"
    
    sentinel monitor mymaster <__IP_MASTER__> 6379 2
    sentinel failover-timeout mymaster 60000
    sentinel auth-pass mymaster <___________PASSW___________>

The log files aren't really informative... is there a way to make it a little bit more verbose? Do you have any idea what am I misssing here?

Thanks in advance!
