[Samba] Debugging tdb_oob log messages in samba 3.6

[John Mulligan]

Hello samba list,

We're trialling Samba 3.6 and on some of our systems I see the following type 
of messages in the smbd and winbind logs:

[2012/03/16 17:28:59.038177,  0] ../lib/util/tdb_wrap.c:65(tdb_wrap_log)
  tdb(/var/lib/samba/messages.tdb): tdb_oob len 663932 beyond eof at 12288
[2012/03/16 17:28:59.038331,  0] ../lib/util/tdb_wrap.c:65(tdb_wrap_log)
  tdb(/var/lib/samba/messages.tdb): tdb_oob len 663932 beyond eof at 12288
[2012/03/16 17:28:59.038408,  0] ../lib/util/tdb_wrap.c:65(tdb_wrap_log)
  tdb(/var/lib/samba/messages.tdb): tdb_oob len 663932 beyond eof at 12288

These messages also appear to coincide with a very long time to open up the 
properties panel of a file or directory on the Windows clients (a mix of Win7 
and Server 2008). I poked around with increased logging levels and did some 
googling but nothing really relevent seems to pop up. 

This feels like a bug to me, but I don't feel like I have enough information 
to report it as such. I'd like to know what to do in order to provide you all 
with more detailed information about this issue. I'm happy to try and provide 
more information, I'm just not sure what is relevant at this point.

Our systems are running Fedora 14 with Samba RPMs of the following versions:
  libtalloc-2.0.7
  libtdb-1.2.9
  samba-winbind-clients-3.6.3
  samba-3.6.3
  samba-client-3.6.3
  samba-common-3.6.3
  samba-winbind-3.6.3

For now we get along with stopping the samba services, and removing 
/var/lib/samba/messages.tdb before restarting them. This clears the issue up 
right away but it "comes back" intermittantly. I have not been able to narrow 
down a cause. Any help would be greatly appreciated.
