Emmanuel Lecharny resolved DIRSERVER-1723.
------------------------------------------
Resolution: Fixed
Solved in the trunk, still an issue in the txns-branch
> Potential LRUCache exhaustion with searches
> -------------------------------------------
>
> Key: DIRSERVER-1723
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1723
> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 2.0.0-M6
> Reporter: Emmanuel Lecharny
> Priority: Blocker
> Fix For: 2.0.0-M8
>
>
> There are many case where the server will freeze if users don't correctly
> close the cursors they get when doing a search :
> - in JNDI, but forgotten to close a NamingEnumeration (*very* frequent use
> case !)
> - when many users create PagedSearches that last for a very long period of
> time...
> - when a client brutally disconnect (no alert will be sent to the server,
> letting the cursor pending until the timeout is reached)
> There is no way we can solve those issues by increasing the LRUCache size.
> The only possible solution would be to allow some search to be proceeded
> outside of any read transaction. That would also imply we deal with ID which
> have been invalidated due to a modification. In fact, a Search should allow
> phantom reads.
> In any case, for internal searches, we should keep a transaction support for
> searches.
