Cassandra crashes every 2-4 days.
The log says:
ERROR [CompactionExecutor:1521] 2018-04-19 10:44:06,691 [url removed, login to view] - OutOfMemory error letting the JVM handle the error:
[url removed, login to view]: Map failed
I changed the heap size from 256M to 8G in /usr/bin/sstableloader but it doesn't seem to help.
