We're running NetStorage 3.1.5-19 on OES 1 Linux, SP2, fully patched via

For the most part, everything works great. Users can log in, download and
update files, etc. However, when they select a checkbox for a folder and try
to download it, the receive an empty zip file. After clicking "download",
there's a pause as thought the system is zipping the files, but the zip file
is empty. If they go into a folder and select multiple (or all) files, they
receive a zip file that contains them. The problem is specific to the
selecting of a folder checkbox for download, it's just like NetStorage isn't
even looking inside the folder when zipping it for download.

Any suggestions? TIA!
