Hi,
I update to sernet-samba 4.1.14, everything started ok, but after I connect the first client and working with files in shares, the process returned with a CPU usage between 90% and 100%. After I logoff the client, the process continues.
I did a 'samba-tool processes' and the process responsible is winbind_server (after pid comparison)
Now, the strace -ff -p have a little difference, some brk() syscalls:
