Andreas Schnitzerling commented on CASSANDRA-8192: -------------------------------------------------- I upgraded to 2.1.2 w/finalizer-patch for CASSANDRA-6283 and tried now the low-environment settings mentioned in CASSANDRA-8070. They didn't change the situation. With 2.0.10 were not any exceptions at the same configuration. Is it better to downgrade back again to avoid any exceptions? Here is the output of nodetool info one minute after start and after 9 Memory-Exceptions: {panel:title=system.log} Starting NodeTool ID : c45a5633-84a0-4196-b2d2-8b3d7060654a Gossip active : true Thrift active : true Native Transport active: true Load : 69,45 GB Generation No : 1415869749 Uptime (seconds) : 85 Heap Memory (MB) : 87,62 / 499,25 Data Center : dc Rack : rack Exceptions : 9 Key Cache : entries 189, size 15,09 KB, capacity 24 MB, 68 hits, 265 requests, 0,257 recent hit rate, 14400 save period in seconds Row Cache : entries 0, size 0 bytes, capacity 0 bytes, 0 hits, 0 requests, NaN recent hit rate, 0 save period in seconds Counter Cache : entries 0, size 0 bytes, capacity 12 MB, 0 hits, 0 requests, NaN recent hit rate, 7200 save period in seconds Token : (invoke with -T/--tokens to see all 256 tokens) {panel} Does it mean, that only 88MB of 499MB are used? > AssertionError in Memory.java > ----------------------------- > > Key: CASSANDRA-8192 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8192 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: Windows-7-32 bit, 3GB RAM, Java 1.7.0_67 > Reporter: Andreas Schnitzerling > Assignee: Joshua McKenzie > Attachments: cassandra.bat, cassandra.yaml, system.log > > > Since update of 1 of 12 nodes from 2.1.0-rel to 2.1.1-rel Exception during > start up. > {panel:title=system.log} > ERROR [SSTableBatchOpen:1] 2014-10-27 09:44:00,079 CassandraDaemon.java:153 - > Exception in thread Thread[SSTableBatchOpen:1,5,main] > java.lang.AssertionError: null > at org.apache.cassandra.io.util.Memory.size(Memory.java:307) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.compress.CompressionMetadata.<init>(CompressionMetadata.java:135) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.compress.CompressionMetadata.create(CompressionMetadata.java:83) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.util.CompressedSegmentedFile$Builder.metadata(CompressedSegmentedFile.java:50) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.util.CompressedPoolingSegmentedFile$Builder.complete(CompressedPoolingSegmentedFile.java:48) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.sstable.SSTableReader.load(SSTableReader.java:766) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.sstable.SSTableReader.load(SSTableReader.java:725) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.sstable.SSTableReader.open(SSTableReader.java:402) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.sstable.SSTableReader.open(SSTableReader.java:302) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at > org.apache.cassandra.io.sstable.SSTableReader$4.run(SSTableReader.java:438) > ~[apache-cassandra-2.1.1.jar:2.1.1] > at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) > ~[na:1.7.0_55] > at java.util.concurrent.FutureTask.run(Unknown Source) ~[na:1.7.0_55] > at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) > [na:1.7.0_55] > at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) > [na:1.7.0_55] > at java.lang.Thread.run(Unknown Source) [na:1.7.0_55] > {panel} > In the attached log you can still see as well CASSANDRA-8069 and > CASSANDRA-6283. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
