Thanks Robert.
I didn't realize that some of the keyspaces (not all and esp. the biggest
one I was focusing on) had RF > 2. I wasted 3 days on it. Thanks again for
the pointers. I will try again and share the results.

Hi,
Below I try to give a full picture to the problem I'm facing.
This is a 12 node cluster, running on ec2 with m2.xlarge instances (17G
ram , 2 cpus).
Cassandra version is 1.0.8
Cluster normally having between 3000 - 1500 reads per second (depends on
time of the day) and 1700 - 800 writes p
We are running 1.2.5 on 8 nodes(256 tokens). all the nodes are running on
same type of machine. and db size is about same. but recently we checked
ReadCount stats through jmx, and found that some nodes got 3 times change
rate(we have calculated the changes per minute) than others.
We are using h

Someone else having what looks like this same issue (in C* 2.0.2 iirc) came
into #cassandra yesterday.

Hi Guys,
Im testing out Cassandra with a 2.0.1 install, just like with 1.2.8 I last
tested, from time to time I am coming across errors that prevent Cassandra
starting up.
For example: Yesterday I installed this instance, created and removed some
“tables” using cql3 and inserted/updated/trunca

Hi,
There is a 12 node cluster , still stuck on 1.0.8.
All nodes in the cluster ring are balanced.
Using random partitioner.
All CFs use compression.
Data size on nodes varies from 40G to 75G.
This variance is not due to the bigger nodes having more uncompacted
sstables than others.

We had a cluster of 4 nodes in AWS. The average load on each node was
approx 750GB. We added 4 new nodes. It is now more than 30 hours and the
node is still in JOINING mode.
Specifically I am analyzing the one with IP 10.3.1.29. There is no
compaction or streaming or index building happening.

Hi Nigel,
I've currently have a simular problem. However, it has only been reproduced on
Ubuntu...
Are you using hsha as rpc_server_type?

I feel compelled to mention that currently, triggers are explicitly

Cassandra 2.0.1
OpsCenter 3.2.2
Java 1.7.0_25
RHEL 6.4
This is a new test cluster with just three nodes, two seed nodes, SSL turned
off, and GossipingPropertyFileSnitch. Pretty much out of the box environment,
with both Cassandra and OpsCenter via DataStax yum repository.
Cassandra seems fine,
In general, my understanding is that memory mapped files use a lot of open file
handlers. We raise all our DBs to unlimited open files.

Investigated a bit more:
-I can reproduce it, happened already on several nodes when I do some
stress testing (5 select's spread over multiple threads)
-Unexpected exception in the selector loop. Seems not related with the
Too many open files, it just happens.

Hi,
We added yesterday 4 nodes in one of our data-centers but met an exception on 2

There's some rationale here:

And I'm sure part of the reason is the 64k size limit: maps (and sets
and lists) are limited to 64k total size
