>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Jim Witschey
>            Assignee: Joshua McKenzie
>              Labels: windows
>
> [~philipthompson] had a look at a few Windows timeouts on CassCI:
> https://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest_win32/86/console
> https://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest_win32/87/console
> https://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest_win32/88/console
> The offending tests were {{bootstrap_test.py:TestBootstrap.killed_wiped_node_cannot_join_test}}
in two runs and {{consistency_test.py:TestAccuracy.test_network_topology_strategy_counters}}
in one. In the latter case, {{killed_wiped_node_cannot_join_test}} passed, so this doesn't
happen 100% of the time.
> Philip has reproduced this locally ({{bootstrap_test.py:TestBootstrap.decommissioned_wiped_node_can_join_test}}),
so it's not purely a CassCI problem. The cause there seems to be an OOM -- when running the
tests, he sees 8GB "committed" in the process explorer, but only 4 actually used.
> I'm opening this ticket to track work on configuring the Windows dtests so this doesn't
happen on CassCI anymore. Assigning [~JoshuaMcKenzie] for the moment, but [~pauloricardomg]
might be able to make short work of this.
