[389-devel] Please review ticket 47936: Create a global lock to serialize write operations over several backends

[thierry bordaz]

Hello,

    This fix allows to protect several backends with a global lock
    during update operations.
    It is configurable and by default the global lock is not enabled.
    Under rare condition some plugin may lead to deadlocks. Global lock
    would be enabled to prevent those deadlocks
    during critical phases or to limit production impact during
    investigations.

      I will do some performance measurement with this fix.
