What does Rebalance failed - mover_crashed mean?

I’m using Couchbase 6.0, one node is at 90% disk space so I’ve added one more node to replace it with.

I have 6 nodes in the cluster and I’ve just added a 7th to replace the low disk node.

But I can’t rebalance the cluster since it crashes with the error message ‘mover_crashed’, do you guys have any ideas?

I really need to replace the node that’s running out of disk space asap

Here’s the full log message:
