----------------------------------

             Summary: Cassandra is shutting down out of no apparent reason
                 Key: CASSANDRA-7786
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7786
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: C* 2.0.9
            Reporter: Or Sher


We've recently start facing an issue when one of the C* node in our dev and CI 
cluster (Thanks god didn't happen yet in Prod) is shutting down from time to 
time without any exceptions or errors.

There is usually something like that in the logs:

INFO [MemoryMeter:1] 2014-08-15 01:32:43,266 Memtable.java (line 481) 
CFS(Keyspace='system', ColumnFamily='sstable_activity') liveRatio is 
14.597030881851438 (just-counted was 14.596825396825396).  calculation took 2ms 
for 84 cells
 INFO [StorageServiceShutdownHook] 2014-08-15 01:40:58,954 ThriftServer.java 
(line 141) Stop listening to thrift clients
 INFO [StorageServiceShutdownHook] 2014-08-15 01:40:59,007 Server.java (line 
182) Stop listening for CQL clients
 INFO [StorageServiceShutdownHook] 2014-08-15 01:40:59,011 Gossiper.java (line 
1279) Announcing shutdown
 INFO [StorageServiceShutdownHook] 2014-08-15 01:41:01,011 
MessagingService.java (line 683) Waiting for messaging service to quiesce
 INFO [ACCEPT-/192.168.27.241] 2014-08-15 01:41:01,012 MessagingService.java 
(line 923) MessagingService has terminated the accept() thread
 INFO [main] 2014-08-17 09:50:56,647 CassandraDaemon.java (line 135) Logging 
initialized

You can see the last line in the log is usually written at least 5 minutes 
before the shutdown, sometimes 30 minutes before.

I can't reproduce it as I have know idea why is that happening and how the 
attack this issue.
I believe I'm not the only one suffering from this issue as there was a thread 
about such behavior in the user mail distribution.


Any thoughts?
