Since 10.9 Apple replaced samba in Lion for their SMBX it's constantly broken. Very broken.
While connecting to a samba share (2012 R2 Essentials) the connections often drops or hangs while this appears in the system.log:
smb2_rq_credit_decrement: Timed out waiting for credits 35
smb_iod_reconnect: Reconnected share <share_name> with server <server_name>
smb_fid_get_kernel_fid: No smb2 fid found for fid 550ff6b0613adf68
smb_iod_reconnect: Reconnected share <share_name> with server <server_name>
A few sources propose forcing using SMBv1 as a workaround like this:
echo "[default]" >> ~/Library/Preferences/nsmb.conf
echo "smb_neg=smb1_only" >> ~/Library/Preferences/nsmb.conf
Which actually makes it work (not hang or disconnect) it's just that a listing of a directory takes 15-30 sec no problem .. meaning it's almost completely useless.
This problem has bothered me for a LONG time now and I'm trying to think of a workaround. One I can think of is compiling Samba (www.samba.org) but as Apple dropped them out of Mac OS X a while ago they don't really make much effort of making samba compatible with OS X .. which is understandable :)
After making some fixes to Samba 4.1.11 source the samba somehow compiles but does not seem to have a mount_smbfs or anything similar - just smbclient.
Does anyone have an idea whether it's possible to make mountning work with OS X (as it involves kernel and I don't know what exactly) ?
Any other propositions on how to fix this?
P.S.: I'm currently stuck at compilation of Samba 4.1.11 version of samba on OS X 10.9.4 with this (if anyone had an idea on how to fix that):

well, thankfully OS X 10.10 Yosemite fixes this and 10.9 does not seem very well supported, so I'm going to assume upgrade is the way to go.
