Hi All,

I am using QNX as a ftp server and there are several FTP clients which will keep doing connecting ,downloading files and
 disconnecting operation.

Initially, inetd is able to start ftpd ,and the ftp client is able to download files.

But after about half hour later, the inetd never listen the port 21 any more.
The ftp client will received "ftp: connect: Connection refused" error message.


I want to kown what will make the inetd not listen the port 21.



Please help me,Thanks in advance.
