dlg99 opened a new issue #3063:
URL: https://github.com/apache/bookkeeper/issues/3063
happens on attempt to create second writer immediately after the first one.
i only was able to repro this by running the whole suite, rtest passses if I
run just this test alone.
Sleep between writer creations helps with the test but probably this worth
looking at.
```
AsyncLogWriter writer1 =
Utils.ioResult(manager.openAsyncLogWriter());
Utils.ioResult(writer1.write(DLMTestUtil.getLogRecordInstance(1L)));
Assert.assertEquals(1L, writer1.getLastTxId());
// some flaky ZK errors after that
//Thread.sleep(1000);
AsyncLogWriter writer2 =
Utils.ioResult(manager.openAsyncLogWriter());
```
```
