Also using the latest version of the driver (1.0.7) is always a good idea
just to make sure you are not hitting issues that have already been
addressed.

You’ll need to provide some more information such as:
* Do you have monitoring on the cassandra cluster that shows the request
latency ? Data Stax OpsCentre is good starting point.
* Is compaction keeping up ? Check with nodetool compactionstats
* Is the GCInspector logging about long runnin
It looks like a memory leak to me. All Cassandra processes are with the
following JVM settings configured: -Xms10240M -Xmx10240M -Xmn2400M. The
OldGen reaches nearly the maximum and it looks like the oldgen objects not
being garbage collected.

Is compaction keeping up? Those replication settings are high - for every
write, 10 nodes are doing something).
What other monitoring stats do you have - what is IO, CPU and network
traffic like? Is the JVM GC activity growing?
Anything else stick out like growing number of network connections to
Hi all,
I've noticed increased latency on our tomcat REST-service (average 30ms,
max > 2sec). We are using Cassandra 1.2.16 with official DataStax Java
driver v1.0.3.
Our setup:
* 2 DCs
* each DC: 7 nodes
* RF=5
* Leveled compaction
After cassandra restart on all nodes, the latencies are alrigh
