samba - May 2010 - Drive becomes unusable with "The group name could not be found"

Out of nowhere the share "neil share" disappeared for one user and the
user got the error "The group name could not be found".  The user was
a
part of the group that was necessary to access the share.  Just
restarting the samba services allowed the users to get back in to the
share.  Not sure what the issue was until then...  Samba version 3.5.2.
