[Samba] winbind stops ? hangs ? & tdbdump problem

[Noel Kelly]

Jeremy,

Great work - no sign of the winbind memory leak now in the latest CVS.  I
have been pounding it since Friday and despite a thrashing today from the
users it looks solid and hasn't blinked.

I think you have been doing some work on the problem with the
winbindd_idmap.tdb file and an old domain ?  When I just upgraded my 2.2.3a
server to the latest CVS it had this in the logs:

[2002/04/15 21:07:29, 1] nsswitch/winbindd_util.c:init_domain_list(152)
  getting trusted domain list
[2002/04/15 21:07:29, 0] nsswitch/winbindd_idmap.c:convert_fn(265)
  winbindd: convert_fn : Unable to find domain NTMIXED
[2002/04/15 21:07:29, 0] nsswitch/winbindd_idmap.c:convert_fn(266)
  winbindd: convert_fn : deleting record NTMIXED/512
[2002/04/15 21:07:29, 0] nsswitch/winbindd_idmap.c:convert_fn(265)
  winbindd: convert_fn : Unable to find domain NTMIXED
[2002/04/15 21:07:29, 0] nsswitch/winbindd_idmap.c:convert_fn(266)
  winbindd: convert_fn : deleting record NTMIXED/513
...ETC

Nice one - although I am a little confused as I thought I was being devious
by manually deleting the NTMIXED stuff (pairs) out of my idmap file this
morning.  Obviously I didn't write it back or something ?  Not sure where
they all came from ?


The other thing I find a little odd is that now 'tdbdump winbindd_idmap.tdb'
just gives me this but there are over 100 users in the system:

[root at belly tdb]# ./tdbdump /samba/var/locks/winbindd_idmap.tdb
{
key = "GID 10048\00"
data = "S-1-5-21-2025429265-764733703-725345543-1643\00"
}
{
key = "UID 10027\00"
data = "S-1-5-21-2025429265-764733703-725345543-1165\00"
}
[root at belly tdb]#


A little disconcerting but winbindd seems to work OK.  Doing the same on my
other server ('liver') it gives me 2000+ lines of output - all the pairings
you would expect.

If I do a 'dump' from inside tdbtool then I get all the expected pairs on
both servers.  Is this a problem with tdbdump ?  Can't see why it chooses to
dump these two records alone on 'belly'.

The idmap file size has also changed a lot. Despite the erasure of the
NTMIXED records it has more than doubled in size:

-rw-------    1 root     root        65536 Apr 15 21:41 winbindd_idmap.tdb
-rw-------    1 root     root        24576 Apr 15 17:37
winbindd_idmap.tdb.orig

Let me know if you want anything from me,

Cheers,
Noel

Are you saying there's a moderate mem leak in the CVS version ?
If so I need to track this down...

How are you reproducing it ?

Jeremy.
