Summary: Memory leak in SerializingCache Key: CASSANDRA-5624 URL: https://issues.apache.org/jira/browse/CASSANDRA-5624 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.1.1 Reporter: Jonathan Ellis Assignee: Ryan McGuire A customer reported a memory leak when off-heap row cache is enabled. I gave them a patch against 1.1.9 to troubleshoot (https://github.com/jbellis/cassandra/commits/row-cache-finalizer). This confirms that row cache is responsible. Here is a sample of the log: {noformat} DEBUG [Finalizer] 2013-06-08 06:49:58,656 FreeableMemory.java (line 69) Unreachable memory still has nonzero refcount 1 DEBUG [Finalizer] 2013-06-08 06:49:58,656 FreeableMemory.java (line 71) Unreachable memory 140337996747792 has not been freed (will free now) DEBUG [Finalizer] 2013-06-08 06:49:58,656 FreeableMemory.java (line 69) Unreachable memory still has nonzero refcount 1 DEBUG [Finalizer] 2013-06-08 06:49:58,656 FreeableMemory.java (line 71) Unreachable memory 140337989287984 has not been freed (will free now) {noformat} -- This message is automatically generated by JIRA.
