>            Reporter: Bogdan Kanivets
>            Assignee: Bogdan Kanivets
>            Priority: Minor
>              Labels: flaky, pull-request-available

> According to the [dashboard|https://builds.apache.org/job/ZooKeeper-Find-Flaky-Tests/lastSuccessfulBuild/artifact/report.html] testFailedTxnAsPartOfQuorumLoss
is flaky. I've looked at some logs and there are multiple causes of flakiness. One of them
is in this line after step 5
> {code:java}
> Assert.assertEquals(1, outstanding.size());
> {code}
> For example [this|https://builds.apache.org/job/ZooKeeper_branch35_java10/10/artifact/build/test/logs]
build of 3.5
> I was able to reproduce this particular issue in debug mode and the problem is that 'outstading'
map can also have 'closeSession' entries that are expected.
> I'll submit a patch to relax this check.
