Nach einem Update auf RC6 (von RC5) lässt ProFTPd immer nur 1-2 Verbindungen zu, danach bekommt man bei einem Verbindungsaufbau ein time out.

Leider kann ich in /var/log/proftpd/* nichts dazu finden, da die proftpd.log leer ist.
In der /var/log/auth.log steht:
Code:
Aug 18 19:49:26 s1 proftpd[14727]: s1.domain.net (::ffff:12.34.56.78[::ffff:12.34.56.78]) - FTP no transfer timeout, disconnected
Aug 18 19:49:26 s1 proftpd[14727]: s1.domain.net (::ffff:12.34.56.78[::ffff:12.34.56.78]) - FTP session closed. ]
Aug 18 20:00:52 s1 proftpd[16951] s1.domain.net (12.34.56.78[12.34.56.78]): PAM(root@domain.net): User not known to the underlying authentication module.
Wodran kann das liegen und wie kann ich es beheben? Danke.
