There were a few reports of errors containing the following exception:
This exception can be thrown in a variety of scenarios generally involving a kernel fault during unsafe memory access.
I've seen an occurence of this issue where the node went into a bad state after a memory access error.
I believe this exception should be treated analogous to `OutOfMemoryException` (
CASSANDRA-13006 ) and cause the process to crash if/when encountered, perhaps guarded by a flag.
