samba - May 2013 - [Announce] Samba 4.0.6 Available for Download : crash of winbind after ls -la ...sysvol

Hi all,

with this version, as in 4.0.5, i have always the windbind crash after
	wbinfo --uid-info 3000000
    or 
	ls -la   sysvol/

my system 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

I already post here some information (no problem with 4.0.4, found last stable
patch with bisect), could someone help me ?

thanks and regards

philippe

Hi

You might try getting hold of one of the Samba developers on IRC and asking
them about this.

Copy and make executable the following script into 
/usr/local/bin/gdb_backtrace
You can add the line panic action = /usr/local/bin/gdb_backtrace

It should give you a backtrace when winbindd is crashing, post this 
trace to samba-technical list.
