From: Andriy Skulysh <Andriy_Skulysh@xxxxxxxxxxx> Client doesn't restore import state correctly on reconnect during replay. It resends lock replay when final ping was queued by server. Server fails with "target_queue_recovery_request()) ASSERTION( req->rq_export->exp_lock_replay_needed ) failed" Add imp_replay_state to store last replay state. imp_state is restored from imp_replay_state during reconnect.
