[Samba] samba freezes the server

Hello List !
oh my....i have a very severe problem here, and i absolutely need
assistance...

my samba version is 3.2.6-3.1-2034-SUSE-CODE11
on an opensuse 11.1 though this thing happened on an ubuntu intrepid
with 3.2.4 too:

the smbd freezes the whole system here.....for no obvious reason
i already tested everything, and everything works perfectly, untill 2 or
more people want to work with it...

- hardware is ok (18h stress test with bonnie, mprime, glxgears, memtester)

- samba basically seems ok too (8 hours of running a script copying 500
mb to a share, deleting them again and restarting the procedure. this
has been done with 400 loops on 3 clients simultanously and everything
was functioning very well.)
Logging in and out, reaching the shares, copying the profiles to the
server...everything is normally ok.

i am labouring on this for about 2 weeks now....and the problem is not
really reproducable it just happens to appear once or twice a day...
the whole system is frozen then and nothing can be done unless you
restart the whole server machine makeing it work perfect

the only relevant info i have on this is that the freeze appeared when
logging out from the domain the last two times, and that i have this in
my logs (loglevel 3):

smbd/notify_inotify.c:watch_destructor(351)
inotify_rm_watch returned Das Argument ist ungültig

and

smbd/error.c:error_packet_set(61)
error packet at smbd/nttrans.c(532) cmd=162 (SMBntcreateX)
NT_STATUS_SHARING_VIOLATION

please help me... This isn't my first samba server...but i am really
going nuts with this one.
Any idea is very welcome...
thank you very much

Sascha

This sounds like a kernel bug to me. An smbd bug can only freeze itself,
not the entire machine.
