Incomplete download

When trying to open a directory on my server the process seems to take forever then times out after a minute then the directory opens but all the files are not visible.
I read where you can go in and change the time out setting and have done so, changed to 120 seconds.
The time out occurs at 120 second and I still don't have all the files.

The log shows this:

[14:46:17] LIST -aL
[14:46:17] 125 Data connection already open; Transfer starting.
[14:46:17] 226 Transfer complete.

after a few seconds but the incomplete list of files in the directory does not appear until after the time expires

Any ideas?
Thanks

Please post the complete log.
