Thanks for all the replies yesterday.

Back to the initial question -- does anyone else have more references or
a working .conf file that is designed, tested and working in an
environment where large files (40-200MB) are being R/W constantly.

I am using Samba (on top of reiserfs/ext3) in a couple of architecture workplaces similar to yours (5-10 users). No errors like yours are experienced and the only non-standard smb.conf settings I use are:

(In the [global] section)
strict locking      = no
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 IPTOS_LOWDELAY

In a couple of other places I am using Samba as a media server for 500meg-2gig file sizes and have experienced no problems there either. In these situations I am using an underlying XFS file system and the majority of tasks are intensive reads rather than read/write.

It would be very strange for Samba to be destroying your disks but I can understand file corruption and locking problems because of the size and nature of the files (AutoCAD seems to try its best to corrupt files on a good day).

I've found most problems like you describe eventually lead their way back to a misbehaving RAID card or driver issue. Either way its not a good position to be in, best of luck and when in doubt simplify :-)
