That's the key:
[2009/03/04 15:51:48, 3] smbd/oplock_linux.c:linux_set_kernel_oplock(138)
linux_set_kernel_oplock: Refused oplock on file Firefox/LICENSE, fd = 28, file_id = fd03:157b181. (Permission denied)
Do you have something like SELinux or so? Or do you share
the files via NFS and some NFS client has the files open? To
work around this problem, you might want to try setting
kernel oplocks = no
in the global section of your smb.conf file.
