I’m on environment with apache Cassandra 3.11.1 with java 1.8.0_144. One Node went OOM and crashed. Re-starting this crashed node is taking long time. Trace level debug log is showing messages like:

Such messages are repeating constantly. I’m seeking help here to find out what may be going on here , any hint to root cause and how I can quickly start the node. Thanks in advance. Regards/asad
