Brandon Williams commented on CASSANDRA-9896:
---------------------------------------------

Working around this by setting commitlog_total_space_in_mb to be less than commitlog_segment_size_in_mb does indeed solve this:

(set to 512 and 1024 respectively)

> See CASSANDRA-9533 for background, specifically the graphs I linked.  Benedict suggests this is due the commitlog recycling and I agree, so the simplest solution is to be able to disable that.
