Native ftpd stopped responding

Tue Jun 1 01:54:40 PDT 2004

I have a FreeBSD 5,1 box  running native ftpd that has stopped responding.
it just stopped one day, without anyone working on ít, or any new installations/configurations.

I cant login to ftp from the network or local

Message: in console:  BIND: addr allready in use
(dont know if it has to do with this problem, because i have seen it before when the ftpd did work)

any clue?
