Explorer & MS Office hang

[Partenheimer Nate]

I'm running samba 2.0.7 on Solaris 2.6.  We've have terrific success for well over a year with samba until about a week ago I started receiving reports that users could not open MS Office docs saved on a samba share.  The samba logs are full of information about oplocks like this:

[2001/03/07 10:14:04, 0] smbd/oplock.c:request_oplock_break(1204)
  request_oplock_break: no response received to oplock break request to pid 2252 on port 33706 for dev = 3180020, inode = 6302796
  for dev = 3180020, inode = 6302796, tv_sec = 3aa6328b, tv_usec = 6168f
[2001/03/07 10:14:08, 0] smbd/oplock.c:request_oplock_break(1204)
  request_oplock_break: no response received to oplock break request to pid 2252 on port 33706 for dev = 3180020, inode = 6302796
  for dev = 3180020, inode = 6302796, tv_sec = 3aa6328b, tv_usec = 6168f

  request_oplock_break: no response received to oplock break request to pid 2252 on port 33706 for dev = 3180020, inode = 6302796
  for dev = 3180020, inode = 6302796, tv_sec = 3aa6328b, tv_usec = 6168f
[2001/03/07 10:14:29, 0] smbd/oplock.c:request_oplock_break(1204)
  request_oplock_break: no response received to oplock break request to pid 2252 on port 33706 for dev = 3180020, inode = 6302796
  for dev = 3180020, inode = 6302796, tv_sec = 3aa6328b, tv_usec = 6168f

smbstatus reports that I have an EXCLUSIVE+BATCH oplock on the file.

Other documents (text, image, audio, etc) work without problems as long as they're not associated with an Office app.  The office files don't seem to be corrupted either - if I ftp them to my w2k workstation I can then open them locally.

I tried setting fake oplocks yes/no but that didn't seem to change anything.

Any suggestions/solutions?

thanks,
