samba - Mar 2009 - vfs full_audit panic

Folks,

I tried using full_audit on Samba 3.0.28 by putting the following
lines on smb.conf (global section):

vfs objects = full_audit
full_audit:facility = LOCAL2
full_audit:priority = WARN
full_audit:prefix = %u|%m|%S
full_audit:success = rename rmdir unlink write
full_audit:failure = none

My log says:

Actually no core is saved on /var/log/samba/cores/smbd, so I cannot
even try to debug it.

Any advices?

Thanks a lot!

Sorry for huge delay. Couldn't avoid it.

Please, how should I run it?

Just valgrind smbd?

Actually, I had never heard of it before.

Very likely that's a bug in that module. For 3.0.28 you
will probably not get support for free here, so your best
bet would be to upgrade to 3.2.8 or better 3.3.2, or talk to
your distribution provider to fix this.

Thanks,

Volker
