two errors

[Félix]

Hello,
    I'ts my first e-mail in this list, so I don't know if I have to do 
something before to write my answer.

    I have installed bind-9.4.1-P1 in a linux machine and I'm getting  
the next errors:

--- 1 ---
Jan  8 05:39:20 ns1.cpd.uva.es named[29113]: [ID 873579 local3.error] 
error: transfer of 'est.cie.uva.es/IN/popTop-publico' from

Could you help me?

Thanks in advance.
