[Pkg-samba-maint] Bug#484235: Bug#484235: panic-action called for /usr/sbin/winbindd

[Jim Barber]

The panic seems to be mostly resolved now.
I used to get this at least once a day, but somewhere along the line, it changed.

However the panics aren't solved. I've had a couple. They look different though so could be due to a different bug?
My most recent occurred on 05 Oct 2008 and it looks as follows:

Then before that I have one on 30 Sep 2008 and it looks as follows:

Next time it happens I'll see if there are any messages in the /var/log/samba/* files.

Interestingly enough the LDAP and Samba packages have not changed version since I was getting crashes:

ii  ldap-utils                  2.4.10-3                    OpenLDAP utilities
ii  libldap-2.4-2               2.4.10-3                    OpenLDAP libraries
ii  libldap-2.4-2-dbg           2.4.10-3                    Debugging information for OpenLDAP libraries
ii  libwbclient0                2:3.2.3-1                   client library for interfacing with winbind service
ii  samba                       2:3.2.3-1                   a LanManager-like file and printer server for Unix
ii  samba-common                2:3.2.3-1                   Samba common files used by both the server and the client
ii  samba-dbg                   2:3.2.3-1                   Samba debugging symbols
ii  samba-doc                   2:3.2.3-1                   Samba documentation
ii  smbclient                   2:3.2.3-1                   a LanManager-like simple client for Unix
ii  winbind                     2:3.2.3-1                   service to resolve user and group information from Windows NT servers

So maybe it was something other dependent library that changed?
Looking through the dependencies above the only packages I can see that has been updated since the last crash were:

- libcups2
- libsasl2-2

But neither of these seem related...
