It was writing to a smb share.

Windows 2003 server 32bit.

Over a terabyte free

None

No error message, it just stopped writing at 1 Gb.  I was doing this using scp.

Well I'm just mounting the volume to FreeBSD from the Windows server so not

I saw posts to that effect and that you needed samba 3.x to support large 
files sizes, and the lfs option.  But the mount_smbfs doesn't offer any 
large file option.

I saw that as an option.  I may try that to test this issue.
