I switched from version 3.8.1 to 4.1 today and noticed a significant delay in loading directories on FTP sites. When I compared the log files, there is a different sequence and the process stalls on the step: 215 NETWARE Type: L8
STAT //GS16/GS16/ for the 4.1 version. If I wait long enough, it does complete the load, but as seen below, the stat info does not show in the log. If I hit the stop (big red icon) button while it is stalled, it immediately shows the directory. I guess that the stop button ends the attempt to run STAT. So I am wondering whether the FTP site is confused by this different sequence of events. The following log files include the lines up to the PASV command.

The first sequence is from 3.8.1:

500 'FEAT' : Unknown Command
USER .westc.w.employee.clemsonu

This is the sequence for 4.1:

The transcript shows that there is no response to STAT //GS16/GS16/workgroupsand the connection is dropped and reopened after the default timeout of 30 seconds. This is an issue with the server software not failing gracefully on a command that it does not recognize at a certain point in the protocol flow. As a workaround, disable the use of STAT.
