Description of problem:
Sometimes a samba subprocess is terminated with signal 11. The locks owned by 
this subprocess are not always freed and the users are beginning to complain 
that files are staying locked even if they shutdown their workstation. 
Restarting the whole samba service fixes this problem but is not a solution 
during the day.

The Samba-server logs the following message:

Some searching on the net reveals that this issue should be fixed in Version 
3.0.23d. 
(http://groups.google.com/group/linux.samba/browse_thread/thread/5ee1c9f2ce51322
1/5f43edd3342ae5be)


Version-Release number of selected component (if applicable):
3.0.23c-2 under Fedora Core 6


How reproducible:
I don't know. I pops up three to twenty times a day.


Expected solution:
Is it possible to update the Samba version shiped with FC6 to 3.0.23d. This 
would fix this issue.
