Everything was working until we tried to update the Master Node from 1.8.8 to 1.8.9.

Here I have some info that I've already collected about everything:

I already had updated Zabbix before with no problems, but this time the server get out of space because of InnoDB and I've lost all Master Node data.
SQL backup was corrupted, I've lost everything on the Master Node database.

There's no problem because didn't affected the slaves and the master isn't so important, but now it doesn't sync anything.

Please, I'm in a hurry, my employers gave me one week to fix it.

I can give any information you need, just ask.

Thank you.

Here are some logs from the slave (filtered):

This time I do have some "OK"s in the log, but still nothing on the Master Node.

The imagem in attachment shows what I say: even in fresh install the data doesn't sync.

And the master only answer this:

In one of the re-installation tries we did get 7 hosts been added, but we've only got NULL on mysql our "Agent droped connection..... ZBX_TCP_READ..." ...
