thx for the answer.

1) the"engineer" fix it yesterday, but it was broken about 6 day.
2) I have 5 slave, and I don't wont (and it's impossible) setup the

i think that enough have a direct connect between master and each 
slaves, and from each slave  to master.

So now we have connect about a day, but number of event (sl_event) is 
grow....
