Jeff Jirsa commented on CASSANDRA-13760:
----------------------------------------
Ran this again and still getting a lot of failures.

Attaching screenshot. I havent had a chance to check them all yet, but I had to
rebase and manually merge in some repair patches anyway, so I'm starting a
clean run again:
https://builds.apache.org/view/A-D/view/Cassandra/job/Cassandra-devbranch-dtest/329/
The fact that these have been pretty messy so far suggests to me there may be a
real problem, though I don't have time to identify it. We'll see if 329 comes
out clean, I guess.
