config fileI've run into a problem copying a 3.6M file from a Win7 client to the linux server via cifs.
Under 2.6.38.2, it only copies the first 64K (exactly) and the client gets a write error.
Using wireshark, in the success case, after the client sends the first 64K, the server response with 4 acks each advertising a Window size of ~48K, followed by an SMB packet acknowledging the first 64K, w/info:
"WRITE AndX Request, 65536 bytes".In the fail case, the server responds with 4 acks, but in each of the 4 ACKS, it's advertising strange window sizes of 881, 1161, 1441 1721 and then responds with a faulty SMB packet w/info:
"[TCP Retransmission] Trans2 Response<unknown>"
Under the Trans2 section it says:Subcommand: <Unknown> since request packet wasn't seen.
----
I originally upgraded from 2.6.35.7 -> 2.6.38.2 and encountered this prob, so successively tried the 26.35.7 config w/2.6.36, 37, 38 and finally 38.1 -- they all work.
The same config on 2.6.38.2 fails as described above.
Config attached.

Not exactly -- Please note -- I tried both 2.6.38(.0) and 2.6.38.1.
They both work.

Any chance that we could get a wireshark trace of the failure?
https://wiki.samba.org/index.php/Capture_Packets
gives instructions. There may also be useful information on
network stack failures returned in the samba log
(often named smbd.log).
