Re: slapd index corruption in low memory situation (ITS#318)
slapd fault handling is wholely inadequate. We would welcome
improvements made in this area. I would suggest that any
coding be done against our devel code as it must pass mustard
there before being applied to 1.2.
It is quite likely that a number of interfaces will have to
be changed to properly report errors up through the stack
so that appropriate high level handling can occur.
I would suggest that further discussion of this issue be
moved to -devel.

I would suggest that an no retry be attempted. The system is misconfigured.
Report it immediately.

slapd should has exclusive access to the db files. If access
is not granted slapd should stop (as it's likely some other
application is mucking with the database).
