Hm.

It seems we have sort of ethernet segment saturation problem.

We have new network environment and the slave does not recognise that he
has no connection to the master.

I set the slave_net_timeout to 5 sec. It's working as an ASAP workaround
but we're investigating the problems behind the network.

Thanks for all.

And you're right: Never upgrade it the system works... :( But we have to
move our whole server infrastructure to another place (had to left the
old ones there).

Thanks again.

A possible bandaid/quick fix is turning on compression for mysql replication.
