> Potential concurrency issue when adding/modifying/deleting entries at a high
> rate
> ---------------------------------------------------------------------------------
>
> Key: DIRSERVER-1377
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1377
> Project: Directory ApacheDS
> Issue Type: Bug
> 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.
