[Proftpd-user] Proftpd leaving wtmp open

[<dat...@gm...>]

Darn was hoping to send this out before 1.4.3c was released (congrats to all for hard work on that)

Anyway, we ran into a problem with 1.4.3b on centos 6.3 where we see that every proftp session leaves the wtmp file open

This results in a problem on high volume FTP servers when wtmp is logrotated out  (and is very large) and there are clients connected (pretty much always have somebody)

wtmp remains open but deleted as reported by lsof (and obvious by df) and remains in that state unless we restart proftpd (thus kicking off all clients which we obviously don't want do)

I haven't tried other FTP servers to see their behavior but do notice that it doesn't appear that ssh sessions leave it open (i.e. they open at connect, close, and re-open on disconnect and close I suspect)
