Not sure if something went awry in this install or something else is wrong, I have a number of ispconfig systems none of which exhibit this issue (but also none are running 2.2.15, only earlier versions). The issue is, when a valid user attempt to login via ftp, the server apparently closes the connection after the correct password is transmitted. /var/log/messages has entries like this: Aug 15 03:59:18 interactive proftpd[25851]: interactive.xxxx.net (xx.xxx.xx.x [yy.y.y.yy]) - FTP session opened. Aug 15 03:59:18 interactive proftpd: PAM (ftp) illegal module type: M-1.0 Aug 15 03:59:18 interactive proftpd[25851]: interactive.xxxx.net (xx.xx.xx.xxx [xx.xx.xx.xxx]) - ProFTPD terminating (signal 11) Aug 15 03:59:18 interactive proftpd[25851]: interactive.xxx.net (xx.xxx.xx.x [xx.xx.xxx.x]) - FTP session closed.

Make sure that you installed all updates for your linux distribution. If there is no update available that fixes the problem, then it might be a hardware problem. Theb you should check your hardware with e.g. memcheck.
