+++ This bug was initially created as a clone of Bug #1109352 +++ This bug is created as a clone of upstream ticket: https://fedorahosted.org/389/ticket/47766 If the tombstone purging thread fires up while a backend has an online import occurring(backend state is STOPPED), the server will crash.
STEPS: Set up MMR. Add large enough number of entries (e.g., 100KB) to make sure the future consumer initialization takes enough time to have tombstone purging while the initialization is running. Set small number (e.g., 10 sec) to these config params on all the servers. nsds5ReplicaPurgeDelay nsds5ReplicaTombstonePurgeInterval Delete some entries. Restart the server. Run consumer initialization. If the initialization is successfully done, the fix is verified.
