------------------------------------------------------------------------

UPDATE: in our case (not the case or the author of the ticket) the JVM was 
crashing. We realised this by enabling Oracle JVM ErrorFile and kernel core 
dumps.
{code}
-XX:ErrorFile=/var/lib/cassandra/heapdump/cassandra-jvm-file-error-1509734684-pid31745.log
{code}

Cassandra 3.9. It happens with OracleJDK 1.8.0_112 and 1.8.0_131. With kernel 
4.9.43-17.38.amzn1.x86_64 and 3.14.35-28.38.amzn1.x86_64

We'll try to share the crash log, but since we are not familiar with its 
contents, we are checking it does not contain any sensible information

> Hello. My company runs a 5 node Cassandra cluster. For the last few weeks, we 
> have had a sporadic issue where one of the servers crashes without creating a 
> dump file and without any error messages in the logs. If one restarts the 
> service (which we have by now scripted to happen automatically), the servers 
> resumes work with no complaint.
> Log files of the time of the last crash are attached, thou again they do not 
> log any crash happening.
> Regarding out setup, we are running these servers on AMazon AWS, with 3 
> volumes per server, one for the system, one for data and one for the 
> commitlog. When a crash happens, we can observe a sudden spike of read 
> activity on the commitlog volume. All of these have ample free space. 
> Aspecially the system volume has more then enough free space so that a dump 
> could be written.
> The servers are Ubuntu 16.04 servers and Cassandra is installed from the 
> apt-get packet for version 3.10.
> It is worth noting that these crashes happen more often when nodetool is 
> running either repair job or a backup job, but this is by no means always the 
> case. As for frequency, we have had about 1-2 crashes per week for the last 
> month.
