---------------------------------------
Summary: Node can be left in a bad state after invalid memory
access exception
Key: CASSANDRA-17223
URL: https://issues.apache.org/jira/browse/CASSANDRA-17223
Project: Cassandra
Issue Type: Bug
Components: Local/Other
Reporter: Paulo Motta
Assignee: Paulo Motta
There were a few reports of errors containing the following exception:
{noformat}{java.lang.InternalError: a fault occurred in a recent unsafe memory
access operation in compiled Java codenoformat} (CASSANDRA-8642,
CASSANDRA-5737, CASSANDRA-11201, CASSANDRA-13091).
This exception can be thrown in a [variety
scenarios|https://stackoverflow.com/a/45536678] 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.
