samba - Jan 2006 - smbclient write error

Can anyone help with the problem I am currently having with using smbclient to
copy from a Solaris box to Windows. My current version of Samba is 2.2.2.

The file is about 800MB, and on different attempts I get different amounts
written but never the full file.

The error message returned by smbclient is "Error writing file: code
0".

I have tried to search for information on this but to no avail. Can anyone help?

Thanks
Matt Noble
