Brandon Williams commented on CASSANDRA-15313:
----------------------------------------------
bq. I do see the timeout on linux with lz4 1.7.1, although I didn't manage to
trigger the crash
You probably need to override the test timeout so it can complete.
bq. +1 on lowering the number of examples to stabilise the test.
I committed the reduction to 35 examples.
