[Samba] Samba shows strange behavior

[Bjoern Meier]

hi,

on weekend I noticed that winbind got terminated (SIGTERM(15) )
without being restarted. So I wrote a script that notifies me when
wbinfo -u returns with an error. So I figured out, that every time I
disconnect from PPtP winbind stops. Today I raised the debug level and
on connect it shows:
[2012/04/25 08:22:30.409693,  3] winbindd/winbindd.c:1188(winbindd_addr_changed)
  winbindd: kernel (AF_NETLINK) dropped ip XXX.XXX.XXX.XXX (<- ppp0 adress)
[2012/04/25 08:22:30.430632,  0]
winbindd/winbindd.c:211(winbindd_sig_term_handler)
  Got sig[15] terminate (is_parent=1)
[2012/04/25 08:22:32,  0] winbindd/winbindd.c:1336(main)
  winbindd version 3.6.4 started.

Why does winbind that?

Winbind is bind to PPtP with ntlm_auth-helper "/usr/bin/ntlm_auth
--helper-protocol=ntlm-server-1
--require-membership-of=S-1-5-21-3000185627-2527819853-479331972-1150"

Greetings,
Björn

PS: no, there is no script on /etc/network/ifup, /etc/network/ifdown
nor in /etc/ppp/ifup or /etc/ppp/ifdown that refers to winbind
