This looks like it might be<>.
 Can you comment on that ticket and share your logs leading up to the error?

Since we upgraded to Cassandra 2.1.12, we are noticing that below happens when we are trying
to bootstrap nodes, and the process just gets stuck. Restarting the process / VM does not
help. Our nodes are around ~300 GB and run on local SSDs and we haven’t seen this problem
on older versions (specifically 2.1.9).

Is this a known issue / any workarounds ?
