Bug Description

Adding the following eventlet.sleep seems to fix the problem (it seems spawning stuff and then killing it before it every gets any cycles causes problems):

    def replicate(self):
        """Run a replication pass"""
        self.start = time.time()
        self.suffix_count = 0
        self.suffix_sync = 0
        self.suffix_hash = 0
        self.replication_count = 0
        self.last_replication_count = -1
        self.partition_times = []
        stats = eventlet.spawn(self.heartbeat)
        lockup_detector = eventlet.spawn(self.detect_lockups)
        eventlet.sleep() # <------------------------ This is the added line
        try:

Workaround is to start the object replicator once there are some objects to replicate.

Also, this doesn't seem to happen with the latest eventlet.
