I seem to have a very strange issue with a pretty simple FTP server
application which works find on older versions of Linux ( e.g. RHEL4 ) but
freezes on Fedora Core 6 and RHEL5 Beta.
The scenario is:

Login OK
Display current directory OK
List current directory OK

The control channel is now frozen and remains frozen until the FTP server
daemon is reset.
It would appear that the control channel works perfectly until the data
channel is used for the first time.  Although the data transferred is
correct, there seems to be an issue is going back to the control channel.

An identical binary on RHEL4 works fine ( as does a version of the code
slightly modified to be a Windows service ).

Any ideas what could be going on ??

Any thoughts or comments would be gratefully received,
