Cassandra terminates on startup

Linux terminates Cassandra on startup. Exit code 137 appears in the /etc/log/kern.log directory and in both Pega Platform Cassandra logs.

Cause

Linux terminates processes that exceed available disk space.

Remedy

Procedure
Provide Cassandra with more disk space by removing obsolete files or by supplying additional disk space.
To remove obsolete Cassandra files, run the nodetool cleanup operation. For more information about adding disk space, see the Apache Cassandra documentation.
