Default ISPConfig FTP Server Issues

Hi guys, i've followed the "Ubuntu 9.10 Perfect Server Guide", and everything is fine.

My Single problem is that the FTP Server goes down like every 2 days, and i have to restart it everytime . I dont know whats going on, could any one give me a hand on this?

Im dissapointed about ubuntu 9.10 , my ispconfig servers running ubuntu 8.04 lts work like a charm from a year now.

Any errors in the syslog when the ftp daemon dies?

But i'm not sure about the FTP daemon described by Timo. I think there is a bug in kernel.
