samba 2.06 caused server self-reboot?

[Winnie Lin]

My samba server (solaris 2.6) self-rebooted few times lately. There was
no apparent hardware problem. When I checked log.smb file. There were
lots of following messages before reboot:

[2000/01/04 16:04:08, 0] smbd/nttrans.c:map_share_mode(410)
  map_share_mode: Incorrect value 0 for desired_access to file \
[2000/01/04 16:04:08, 0] smbd/nttrans.c:map_share_mode(410)

[2000/01/04 16:04:09, 0] smbd/nttrans.c:map_share_mode(410)

What do the above messages mean? And could it cause server to
self-reboot? Thanks,
