Sergey Chugunov commented on IGNITE-8131:
-----------------------------------------
[~garus.d.g],
I double checked your result and managed to reproduce the issue locally: I've
run this single test with "Until failure" configuration and observed failure on
120th execution.
I found another detail about failure: in all successful executions ZooKeeper
client is closed because of session timeout reported by this line in logs:
{noformat}
[WARN ][zk-client-timer-internal.ZookeeperDiscoverySpiTest1][ZookeeperClient]
Failed to establish ZooKeeper connection, close client [timeout=2000]
{noformat}
But in failed execution I don't see this line in the logs. It looks worth
investigating what causes this behavior and its implications.

> It is possible to reproduce test failure locally as well, but with low
> probability: one failure for 50 or even 300 successful executions.
