samba - Aug 2002 - oplock_break messages in logs after 2.2.5 upgrade

Since I upgraded my servers from 2.0.10 to 2.2.5, I am gettting messages
logged about oplock_break failures. Can I just ignore these? Nobody has
reported any difference in performance. I haven't changed the default
logging level in smb.conf, can I change it so it ignores these messages w/o
missing something else important?
