[Samba] winbindd panic daemon dies

Hi All,

	can anyone make any sense of the error below, please advise if I need to log

This is from my winbindd log file,

[Samba] RE: winbindd panic daemon dies

also getting the error below, can anyone tell me what winbindd is using for
resolving the network address of the kerberos server? It is resolveable by DNS
and the server is up,

Yes it's a bug. What would really help is a stack backtrace
from a winbindd compiled with -g stuck on a panic action (see
the smb.conf manpage for this parameter).

Thanks,

Hi, 

	I haven't been able to work out how to capture the backtrace, I've
installed winbind with debug compiled and also gdbm. I get the output shown
below, what do I need to do next?

It is DNS, per the standard kerberos way of doing things.  That often
doesn't quite work right, and so you can define up the [realms] section
of your krb5.conf to give the krb5 libs a better idea.

(Even if that fixes it, we still really want to see the backtrace).

[Samba] RE: winbindd panic daemon dies

Hi, please find attatched the back trace from my winbindd (samba 3.0.0) panic,

I hope you mean gdb - the GNU Debugger, not the database :-)

If you look in the manpage for smb.conf, you can setup a 'panic
action'.  This can do anything from popping up gdb in an xterm to
mailing you a backtrace.  

The example in the smb.conf is 

panic action = "/bin/sleep 90000"

This makes winbind just hang in there, so you can attach the debugger

Then you can attach gdb in the normal way:

gdb /path/to/samba/winbind 2348

where 2348 is the pid of the near-dead winbindd.

Run 'bt full' and give us the result.

[Samba] RE: winbindd panic daemon dies

I had the same problem last night using 3.0.0-1 on RH 9. It is connecting
via a slow link and seemed to panic when we started pushing a nightly backup
across the link. 

I can run valgrind on it if that would help. Was the stock RPM compiled with
debug?

regards
Stephen Collier

It probably was (an error in the release, actually) but rpm stipped
it...

A valgrind run would help.

[Samba] RE: winbindd panic daemon dies

Hi Andrew,

	I don't think Sun provide and malloc debug libraries. On the linux box it
is possible but, I'm not an experienced linux user, I'll need to source
a machine for this, it'll take me a while,

		thanks Andy.

panic,
Bugger - it's another malloc() related bug.  That means that some free()
call - sometime before this one, was misused.  If you were running it on
linux, I would suggest running winbind under valgrind, but there might
be some other ways to help track this down:

Are there any debugging malloc libraries for Solaris?  

Is it reasonable to try and setup a linux box in a matching setup?

[Samba] RE: winbindd panic daemon dies

I now have a valgrind dump of a panic. There are several normal starts and
stops as I am restarting winbind at 6:00 am every morning when the server
syncs are stopped.

I hope this helps
