Stefania commented on CASSANDRA-11534:
--------------------------------------

The tests are fine now. To fix them I had to rebase my driver patch from the 
_cassandra-test_ branch to the 3.6.0 release tag, so something on that branch 
is causing some insert requests not to be acknowledged, possibly due to errors, 
this in turn causes the tests to hang. It may be related to the recent protocol 
version 5 changes.
