samba - Jun 2015 - macos finder error 36 when copy folder to samba 4.2.2

dear list,

encountered a problem and hopefully someone more experienced might help me.
problem is with macos 10.9.5 and finder.

i want to copy a simple folder with subfolders and without any files to 
my samba share.
files work flawlessly.

when i drag a folder from desktop to share the finder errors out with 
error -36 but creates all folders.
same happens when i copy an empty folder from the share to the share.

macos log says:
16.06.15 17:19:54,000 kernel[0]: smb_ntstatus_error_to_errno: Couldn't 
map ntstatus (0xc0000225) to errno returning EIO
16.06.15 17:19:54,000 kernel[0]: smb2fs_smb_cmpd_set_info: Second close

appended a pcap file with port 445 capture of the copy operation.

target folder posix-permissions are 0777 and acls are also rwx for user, 
group and others
as well as default acls for group @support with rwx
