The server has a reverse dns address, it can't be problem.
The strange thing: It had been good until the last week, I didn't changed or
upgraded anything before crashes.

I suspected the nfs because there weren't any other message in the log
files.
One of these freezes, I was loged into the server over ssh and suddenly the
mashine didn't answer my commands.
After this, every opened ports gone away. And as I said, the sshd and
proftpd banner saw in telnet client but the auth. didn't work.
