URL: https://issues.apache.org/jira/browse/CASSANDRA-10449
Project: Cassandra
Issue Type: Bug
Components: Core

I have a 20-node cluster with vnodes (default of 256) and 500-700GB per node.
SSTable counts are <10 per node. I am attempting to provision additional
nodes, but bootstrapping OOMs every time after about 10 hours with a sudden
long GC pause:

no avail.
