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?

all i got in syslog is

Code:

many times, i dont think that this has to be with the ftp daemon right?

I have the same problem.

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