I'm running Cassandra 4.0.8 on CentOS Stream release 8, using Java 11.0.17. When I cleanup after a bootstrap some of my nodes crash. Basically it seems to crash when streaming and compacting a lot of data.
I believe to be using the latest Java 11 VM and the latest Cassandra 4 versions.
Would anyone have any suggestions on how to fix this problem. I cannot reproduce the problem on demand, it happens sometimes when there is lots to do.!!
Thanks for your help,
Jean
