------------------------------------
Summary: Heavy write load exhausts heap space
Key: CASSANDRA-6056
URL: https://issues.apache.org/jira/browse/CASSANDRA-6056
Project: Cassandra
Issue Type: Bug
Environment: Debian, Cassandra 2.0
Reporter: arnaud-lb
Issuing many INSERT or UPDATE queries cause cassandra to exhaust the heap space
in a few minutes. It then gets stuck in full GCs, failing to recover.
Observed with the default config from Datastax Debian packages, with a 8GB
heap. Query rate is around 35K queries per second, with 16 concurrent queries.
