> Bootstrap of new node fails with OOM in a large cluster
> -------------------------------------------------------
>
> Key: CASSANDRA-14840
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14840
> Project: Cassandra
> Issue Type: Bug
> Components: Streaming and Messaging
> Reporter: Jai Bheemsen Rao Dhanwada
> Priority: Critical
>
> We are seeing new node addition fails with OOM during bootstrap in a cluster
> of more than 80 nodes and 3000 CF without any data in those CFs.
>
> Steps to reproduce:
> # Launch a 3 node cluster
> # Create 3000 CF in the cluster
> # Start adding nodes to the cluster one by one
> # After adding 75-80 nodes, the new node bootstrap fails with OOM.
