[Samba] Samba 3.0 persistent locked files

[Jaap van Geels]

I migrated an existent domain, about 70 NT4 + some XP clients to Samba.
Redhat 9, Samba 3.0, Single server configured as PDC.

A major problem that occurs is that often files that are locked, stay 
locked even after the client pc reboots. Users cannot access the files 
anymore and Samba has to be restarted.

Workarounds I created are:
- stop/start samba at night and "rm -f /var/cache/samba/locking.tdb" in 
between.
- disable locking on some shares like homedirs were I expect only one 
user at a time.

Is this a configuration error or known issue? I cannot find anything 
like this searching google(groups).

TIA for any help.
