[Samba] Errors in samba 2.2.4

[Netikular]

I just downloaded and installed samba 2.2.4 on freebsd 4.5.  I am running
this freebsd server as a PDC and file storage server for 4 windows 2000
computers and 1 windows 98 (the win98 computer is not part of the Domain)

I was wondering if anyone has any suggestions as to what would cause errors
of the following types

oplock errors
[2002/05/06 12:06:08, 0] smbd/oplock.c:oplock_break(758)
  oplock_break: receive_smb error (Connection reset by peer)
  oplock_break failed for file Databases/IPV Invent.mdb (dev = 37406, inode
= 6578201, file_id = 113).

  request_oplock_break: no response received to oplock break request to pid
54124 on port 1886 for dev = 37406, inode = 6578201, file_id = 113

and read failures.
