We are running 0.8.7. No big issues so far.
Thanks,

Yes, mostly sounds like it. In our case failed repairs were causing
accumulation of the tmp files.

Tombstone is a marker indicating the record to be deleted.
"gc_grace_seconds" is the time after which the record will be deleted
physically from the node.
There is no ad-hoc way of gc'ing tombstones. Only after "gc_grace_seconds"
the tombstones will be gc'ed.
Thank
That will give you a snapshot of thread pools. You should look at
ROW-READ-STAGE and see pending and active. If there are many pending, it
means that the cluster is not able to keep up with the read requests coming
along.

Do you use any client which gives you this timeout ?
If you don't specify any timeout from client, look at rpc_timeout_in_ms.
Increase it and see if you still suffer this.
Repair is a costly process.

Hmm..What's the data distribution like on cluster? R.P.?

I am not so sure from version to version.
1. Which client are you using? Any custom load balancer?
2. Is the hardware on this node any different from other nodes?
Thanks,
Jahangir.

Mostly, they are I/O and CPU intensive during major compaction. If ganglia
doesn't have anything suspicious there, then what is performance loss ?
Read or write?

Memtable live ratio is fixed between 0 and 64. It's reset to 64 once live
ratio reports a higher value. It's between 0 and 64 for health of the node.

There is something wrong with the system. Your benchmarks are way off. How
are you benchmarking? Are you using the stress lib included?

IMHO, you should start with something very simple RDBMS and meanwhile
getting handle over Cassandra or other noSql technology. Start out with
simple, but always be aware and conscious of the next thing you will have
in stack. It's timetaking to work with new technology if you are in the

Have this weird issue. Initially, it was jvm crashing with Segmentation
fault errors. Once I updated it, it did solve the problem that jvm isn't
crashing. This time cassandra process just dies without any warning in the
logs.
To note specifics of the node:
98GB RAM
400 GB Disk Space
Currently used
Thanks. Will try upgrading jvm.
Is 1.0 or 0.8.6 is backwards compatible with 0.8.1?
Thanks,
Jahangir.

Hello All,
JVM is crashing on the cassandra nodes. Re-start doesn't help for long.
