[Samba] smbd's using up 100% of all cpu's and load avg slowly going up

Hi,

Yes, I already thought about it.

I have the sernet repo installed.. Is possible to yum update and jump
from 4.1.6 to 4.1.14 directly, without problems or should I follow some
kind of procedure to avoid future problems?

Regards,
Bruno Andrade.

I would back everything up, then carry out the update/upgrade. To be 
honest, I do not use the sernet packages, but I did upgrade from 4.1.9 
to 4.1.11 on Debian backports without incidence.

[Samba] smbd's using up 100% of all cpu's and load avg slowly going up

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:
fcntl(13, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=29212, len=1}) = 0
brk(0x7f99e70d9000)                     = 0x7f99e70d9000
writev(44, [{"\250\r\0\0\2\0\0\0S-1-5-21-2097307442-3435"..., 3496}],
1) = 3496
epoll_wait(9, {{EPOLLIN, {u32=3862499424, u64=140298969223264}}}, 1, 30000) = 1
readv(34, [{"0\10\0\0", 4}], 1)         = 4
