Successful Backtrace RE: Another RE: 2.2.3pre winbindd crash

[Noel Kelly]

Success - Got the backtrace from the last winbind crash.  Doesn't mean a
whole lot to me but I hope it helps you guys.  Something to do with these
rid 512 errors I am getting in the winbind log (log below) by the look of
it:

Just had another winbind crash - but the panic action did not trigger.  No
messages in the logs so it never even attempted the panic shell script.

I'll give it another chance and then try the sleep option.

Same rid 512 (Domain Admins) is repsonsible.  Could this be a problem with
the upgrade from 2.2.2 to 2.2.3pre ?  The only file I bought across was the
winbindd_idmap.tdb.  And I rejoined the domain and secret is good.  All
these "could not get domain sid for domain @UK" worry me as I don;t
understand where they are coming from.  Winbind functions fine (until it
bombs).

Looks OK - make sure you can display an xterm from root's shell.
I do xhost +localhost and xterm -display localhost:0
