[Samba] One file open or locked way too many times. How to fix?

[Aaron Kincer]

I saw similar behavior with Access. The issue is now gone and it just so 
happened to coincide with when I fixed some ACL and DOS attribute 
issues. I did this by turning off the map archive, map hidden, map read 
only, and map system settings and used nt acl support, ea support and 
store dos attributes instead. I don't know if this was what fixed the 
issue or not, but after I resolved the ACL issue and turned off the 
mapping of all the dos attributes, the problem disappeared. I wish I 
could have done some exhaustive testing to know if this was the fix, but 
my primary goal was to fix the ACLs. Once I did that and the Access 
issue went away, I decided not to spend time chasing it unless the 
problem came up again.

In my log files, I saw repetitive and very rapid opening and closing of 
the database file (watched via tail -f). The opening and closing only 
happened as the database was being modified (i.e. they were typing 
inside an Access form). Not sure if that is the kind of behavior you are 
seeing. Merely having the database open didn't cause the issue.
