I have problem with reproducible memory leaks in 1.0.5 - node ends with
OOM, it worked fine with 1.0.3. Can someone write guide how to report
memory leaks - i can collect jmap dumps. It would be best to write wiki
page about it.
I am not happy with 1.x branch stability. It has memory leaks
Hi Jeremiah,
The thing is I will send the data to a massive storage facility (I don't
know what's behind the scenes) so I won't be backing up on one machine
where I can install Cassandra. Does the sstable loader work just for
copying data from a Cassandra cluster to somewhere on a disk where
Hi, I'm running a 4 nodes Cassandra cluster, and I'm facing the same
problem (node not present on nodetool ring, but unreachable on CLI describe
cluster...). I'm currently running version 1.0.2, but I have update from
0.8.x, the problem may exist since a while, I don't really know. I can't

My understanding was that total is sum of all SSTables on disc even those not
being used currently and live is the sum of the SSTables on disc that are
being used currently.
Well I have a Cassandra 1.0.2 cluster in which all of the column families
are reporting live being greater than total. I
Hi,
I am thinking of strategies to deploy my application that uses a 3 node
Cassandra cluster.
Quick recap: I have several client applications that feed in about 2
million different variables (each representing a different monitoring
value/channel) in Cassandra. The system receives updates for
That version of Cassandra had a bug where it was using the wrong size
especially if someone is using compressed tables.

Currently, the syntax for creating column families is like this:
create column family Users
with comparator=UTF8Type
and default_validation_class=UTF8Type
and key_validation_class=UTF8Type;
It's not clear what comparator and default_validation_class refer to. Much
clearer would be:

Once you get all of the data on one machine you can then
flush/drain/compact shutdown the single node and then take the data
folder off that machine and back it up. Then when you get your new
cassandra cluster setup you can use the sstable loader to shoot the data
from the backup into the new
Aha. I just tested that. Good point. It just seems that way because if I do
not clear my snapshots in production I run into disk space issues rather
quickly. That is what happens when you assume.

Sounds like you're simply throwing more seq scans at it via m/r than
your disk can handle. iostat could confirm that disk is the
bottleneck. But real monitoring would be better.

Possible, but unlikely.
Do you have any pointers on how to resolve this? We can see no
issues reported in the syslog or on the RAID or ESXi. We changed the
filesystem from xfs to ext4, still we get the same error. I am
attaching some more signatures here in case anyone has any comments..
