[Samba] Connection dropped when copying large files

Just another clue for you:
The samba crash/lockup appears to happen at the END of a large file write.
I can write 2gb or 65gb files across the lan to the samba share, but when
the file is (or is about to be) closed, samba locks up the share.
I already tried with NO socket options - same results....

Recent thinking is that so_rcvbuf & so_sndbuf are probably not needed
anymore and may actually degrade performance. Try commenting them out & test
