This is the root of the problem:

[2014/09/24 16:15:04.433393,  2, pid=2495, effective(547, 500), real(547, 0)] ../source3/smbd/smb2_server.c:1784(smbd_smb2_request_v
+erify_creditcharge)  CreditCharge too low, given 1, needed 2

Can you log a bug with the samba bugzilla and
also upload a wireshark trace of these packets ?

We'll need that to investigate & fix.

Thanks !
