Summary: Cassandra 3.10 crashes without dump Key: CASSANDRA-13663 URL: https://issues.apache.org/jira/browse/CASSANDRA-13663 Project: Cassandra Issue Type: Bug Reporter: Matthias Otto Priority: Minor Attachments: 2017-07-04 10_48_34-CloudWatch Management Console.png, cassandra debug.log, cassandra system.log 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. 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
