> I have a dtest that fails intermittently because of SSTable leaks. The test logic leading
to the error is:
> - create a 5-node cluster
> - insert 5000 records with {{stress}}, RF=3 at CL=ONE
> - run {{flush}} on all nodes 
> - run {{repair}} on a single node.
> The leak is detected on a different node than {{repair}} was run on.
> The failing test is [here|https://github.com/mambocab/cassandra-dtest/blob/CASSANDRA-5839-squash/repair_test.py#L317].
The relevant error his [here|https://gist.github.com/mambocab/8aab7b03496e0b279bd3#file-node2-log-L256],
along with the errors from the entire 5-node cluster. In these logs, the {{repair}} was run
on {{node1}} and the leak was found on {{node2}}.
> I can bisect, but I thought I'd get the ball rolling in case someone knows where to look.
