Hi! I have a work Samba file server on Ubuntu Server 12.04. I can successfully add small files to it like docs and pdfs. However when I try to add a large file, for instance a 1.2gb video file, the server appears to timeout after appearing to be halfway completed. What can I do to solve this error? I looked into the logs and this is apparently what occurred:

smbd/process.c:244(read_packet_remainder)
read_fd_with_timeout failed for client 0.0.0.0 read error = NT_STATUS_CONNECT$

How can I resolve this to allow for these bigger files to be transferred to the server? Thanks!
