| Doc Text: |
Starting a long running task in the server (using the cn=tasks,cn=config interface), then shutting down the server before the task can complete, caused the server to crash. This update prevents the server from crashing, but does not gracefully terminate the task, which can leave the server database in an inconsistent state. For example, the fixup-memberof.pl script invokes a tasks to fix up the memberOf attribute in group member entries. If the server is shut down before the task can complete, some entries may not have the correct memberOf values. The user should ensure that the task is complete before shutting down the server to avoid inconsistency.
