[Samba] What circumstances migth favour frequently locked files

Gentlemen, I am running a RH9 - Samba PDC ( 3.0.1pre3) in a mixed
W9X/XP/NT production environment and encountered a problem related to
locked files. By tracing down the event I suspect it might have happened
when a certain user tried to copy a large number of files from an NT
server on to the Samba server.  The process resulted in a list of locked
files that remained there until a smb restart. Below is my event log
related to that. 

However I discovered other files staying locked as well , not in
relation with big transfers . 


Can you please tell me what circumstances might favour such unwanted
locking situations? And what are the odds for file corruption in such


And final question:  What is the safest upgrade method from a
preliminary version - rpm package - ( 3.0.1pre3, my case) to the latest
stable one?  Simply removing the rpms and installing the new ones by
preserving the conf and smbpasswd file?


Thank you,
