Emmanuel Lecharny commented on DIRSERVER-1377:
----------------------------------------------
I have substituted the current AvlTree we were using to store duplicates in
index by a simpler array of Objects, as I suspect a bug in the way we handle
AvlTrees in very specific cases to be the cause of the problem we have.
So far, tests seems to be ok, as I was able to inject more than 1 500 000
entries in the server without problem (20 concurrent threads creating and
deleting entries concurrently).
I will probably commit the change tonite.

> Affects Versions: 1.5.4
> Reporter: Emmanuel Lecharny
> Priority: Blocker
> Fix For: 1.5.5
>

> When adding/deleting entries with many clients (a client add and delete an
> entry many times), we may have some concurrency problem, as the index are
> updated without concurrent acces protection.
> Synchronizing the classes where we update the index might help.
