Can't copy large files to any Samba share

Just updated to Mavericks but i'm having big problems moving bigger files (so far i've tried a couple of 4GB files) to a SMB share. Just the other day i could copy these files over just fine under Mountain Lion but Mavericks throws this error:

"The item blablabla.bla can't be copied because it's too large for the volume's format"

So far i've tried with a couple of files smaller than 4GB (up to 2.5gb so far) work just fine. No write errors either. The files can be copied without problems when i boot from my older harddrive with Mountain Lion still on it so i'm going to go out on a limb and say it's not a file or server error but a Mavericks error. Anyone know why or what to edit for this to work normally again?

OS X Mavericks (10.9)

I'm also seeing this error. It's not just SMB it's AFP shares too.

Just to confirm I am also seeing this error.

Was able to copy lare files, in excess of 18Gb to a SMB share. Immediately after upgrading to Mavericks, I'm unable to copy even an 8Gb file. My MacBook Pro which is still on Mountin Lion doe not have the same issue copying the same file to the same location.

I have temporarily resolved this problem by reconnecting to the server and shares differently.

Disconnect from the server
In Finder, select "Go" and then "Connect to server..."
For server address enter: CIFS://ServerNameOrIPAdress/
Select the shares you need

You will now be able to move bigger files to SMB shares again. For ease of use, drag a share or a folder within a share to your Sidebar.

As it appears Apple has implemented a newer version of the SMB protocol, SMB2, that is still somewhat buggy and will throw errors like these.

I hope this helps someone else as well.

This was only a temporary fix for me. Worked for one go around and then the same error returned. Even tried disconnecting again and reconnecting, no go.

I can confirm that I am experiencing this problem as well, seemingly very patchy connection to samba, throwing an error 51 a lot. For me it's large and small files, copying to and from samba drives over the network
