slow start of ftpd

[mempheria]

Hi 

My ftpd is unstable, sometiems it works to login via ftp and sometimes not. once i get in it works just fine! i think the problem occure when i reboot/just start my machine, sometimes i have to wait for after 5 minutes when the machine is up and running before i can login.

any clues?

system information: 

ftpd = FreeBSD´s default ( eh name?)
BSD version = 5.0

and... its the same machine i try ftp from  ( so its not client error )

Thanks in advance
