Hi all,
thanks for the help. the issue happened again. I looked into Romain's
suggestion and yes, it was VMware balloning.
So, i will not be updating the jira ticket as I am not sure if the fix
actually helped or not.
Thanks,
Prem

Thanks Robert. That seems to be the issue. however the fix mentioned there
doesn't work. I downgraded Java to jdk6_37 and that seems to have done the
trick. Thanks for pointing me to that Jira ticket.

en if they are not
loaded?
If the nodes are VM you have to pay attention to hypervisor memory
overcommit.

Also we use datastax. The version cassandra-1.1.9 doesn't work with java 7

The output of ps waux . Also there is no load on cluster. None
USER PID %CPU %MEMVSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 19224 1076 ?Ss Mar19 0:01 /sbin/init

Is there anything else running on the boxes? Can you show us the output of
ps aux for the Cassandra process so we can see the -xmx, etc? JDK 7 may
help, even if you cannot upgrade Cassandra yet (which I would really
recommend since it moves items off-heap).

Upgrading is not possible right now. Any other suggestions guys?
I have already tried reducing the number of rpc threads. Also tried
reducing the linux kernel overcommit.

I ran into the same problem some time ago.
Upgrading to Cassandra 2, jdk 1.7, and default parameters fixed it.
I think the jdk change was the key for my similarly small memory cluster.

Michael, no memory constraints. System memory is 4 GB and Cassandra run on
default.

Its Oracle jdk 1.6.
Robert, any fix that you know of which went into 1.2.15 for this particular
issue?

Try using 1.2.15, instead?

What JVM are you running on? What, if any, memory constraints are you
passing to the process?

Hi,
I have a 3 node cassandra test cluster. The nodes have 4 GB total memory/2
cores. Cassndra run with all default settings.
But, the cassandra process keeps getting killed due to OOM. Cassandra
version in use is 1.1.9.
here are the settings in use:
compaction_throughput_mb_per_sec: 16
row_cache_
