I'm pretty sure that your answer is going to be "no".

Most of my experience with SMBFS comes in the opposite direction - 
trying to write large files to an SMB-mounted filesystem and that was so 
problematic that we switched to NFS.  That's a bit more work to set up, 
but well worth it, imho.

So far, fingers cross and touch wood, with Windows virus checking turned 
off on the remote drive, writing large files has been problem free and 
tests reading those files have had no problems either.  Only talking in 
the 40Gb range though.

PS The problems we experienced didn't include wedging, iirc.  Files 
would fail to rename, but if you waited 30 seconds and looked for your 
target file, it would, hey presto, have appeared.  But writes also timed 
out, taking, in this case, a backup job with it.
