Description Thomas Thiel 2007-01-04 08:14:48 UTC 
While accessing the Security Settings on a windows XP client, the accessed Samba server crashes. this crash results in a hanging Security dialog, which will eventually recover, but without resolved SIDs.

The Server runs with security=domain, but the error also occurres with security=ADS. At first the problem occurred after an update from Samba 3.0.2a to 3.0.23d. File Serving does work perfectly anyways, the user are just unable to change any permissions of their files.

I'm using winbindd to resolve the usernames on the serverside, which are served by two native Win2003 Servers. lookup and SID-user/group mapping works perfectly when checked through wbinfo.

Here is a log of the dump:

Its a productive Server which did work perfectly with the old samba version, using the same configuration. I would be very thankful for quick help...
Comment 1 Volker Lendecke 2007-01-04 08:47:47 UTC 
Can you upload a debug level 10 log with a few thousand lines prior to that crash?

Is it possible that you recompile with -g so that we get better stack traces? And, if possible it would be extremely helpful to run smbd under valgrind with the -g compile. I'm pretty sure that if I get that output the fix will be trivial.

Thanks,

Volker

(In reply to comment #1)

OK, here you are, a loglevel 10 cutout of crash. If this will not help, I could recompile with the -g option, but would like to circumvent this, as this server is in productive use, with user who will get unhappy with their smb connection getting lost due to server restarts. ;)

I will attach the log to this bug.

a few thousand lines of level 10 log of this bug
Comment 4 Thomas Thiel 2007-01-04 09:20:48 UTC

level 10 log of the same problem, but without the smbd crash

this log resulted in a try to replicate the problem, which resulted in a list of unresolved SIDs on the client side, but this time without a panic of smbd.
Comment 5 Volker Lendecke 2007-01-05 06:24:44 UTC 
I'm afraid I still don't see how this can happen. Further option: Get the valgrind log with -g which is not guaranteed to give results, or somehow get me enough info to reproduce it. But to be honest, I don't know how...

Next option: That code has changed slightly for 3.0.24. So you might try the 3_0_24 branch on a test machine.

Samba 3.0.x is not supported anymore.
