I have NW6.5 server running BM3.8 Sp1. Just recently started getting
issues with file downloads over both http and ftp. Browsing is still fine.

When trying to download especially over ftp the process will start and
eventually end in a 504 error. Quite often files will reach 97 - 99%
complete and then just timeout.

I dont believe anything has changed config wise.

Any ideas ?
