[Pkg-samba-maint] Bug#405198: samba: common tdb corruption in locking.tdb and connection.tdb

[Jamie Thompson]

Package: samba
Version: 3.0.23d-2+b1
Severity: important


I'm getting regular corruption of the tdbs (and the associated panics)
in my logs. I stop the daemons, clear out /var/run/samba and restart,
but this always happens fairly soon.

Here's a snippet:
[2007/01/01 16:18:03, 0] tdb/tdbutil.c:tdb_log(783)

...and from one of my other workstation's logs:

Let me know if you need anything else. I've got nothing fancy in my
smb.conf, so it seems pointless including it.
