[Samba] INTERNAL ERROR: Signal 11 in pid 8928 (3.0.23c)

Hello!

It seems my struggle with Samba isn't quite over.  My latest problem is
exactly what you see above, followed by an attempt to core dump.  This
occurs upon authentication to the system.  My system is part of a W2K3
domain.  I looked at the Samba HOWTO, but apparently I have a system
(FC5), that doesn't allow core dumps when the PID changes, since no core
dumps are being created.  Also, smbstatus doesn't give me a PID, so I am
having a hard time running gdb to further understand this issue.  Here
is the log output:

I'm running:

Any ideas on this?

Thanks!

For a core dump, add the lines :

panic action = /bin/sleep 999999

to the [global] section of your smb.conf, and
reproduce the problem. The smbd will hang waiting
for the sleep to finish, allowing you to attach
to the waiting smbd process with gdb. You can then
print out a backtrace with symbols which is a much
more helpful review of the problem.

Thanks,

	Jeremy.

[Samba] INTERNAL ERROR: Signal 11 in pid 8928 (3.0.23c)

Hello Nolan,

I'm experiencing exactly an error similar to yours, except I get no
"core
dumped" message, just a more vague "canceled" message. What
distro are you
running? I'm getting this with Ubuntu's samba packages (I haven't
yet gotten
around to trying it on another distro, but will do so tomorrow probably).

To Jeremy: sorry for the noobish question, but how can I attach gdb to the 
process? 

Here is the output I get:
# smbd -i
smbd version 3.0.22 started.

This is a bug in the MDNS library from what I remember.
Remove mdns from hosts in /etc/nsswitch.conf

Removing mdns did indeed fix the problem.
Thanks a lot Jerry
