Attached is a zip file with logs from running opennms-rrd-stresser

Could you show us how you configured and setup the environment and ran
the RRD Stressor?
I included the shell scripts I used to run the stresser in the zip for
each strategy.
/usr/java/jdk1.7.0_06/bin/java -jar -Xmx1024m \
-Ddebug=true \

I had two directories that I had compiled things in, so that's why
CassandraRrd used a different directory path than JRobinRrd and JniRrd.
I had originally had a problem running the JRobinRrd strategy (it ran
the CassandraRrd), but once I moved my /opt/opennms directory out of the
way, it worked as expected.
For the VirtualBox configuration, it has 8GB of base memory, ICH9
chipset, IO APIC, 8 processors, 100% execution cap, pae/nx enabled,
vt-x/amd-v enabled, netsted paging enabled. The are two VDI disks on a
SATA controller, both dynamically allocated. The OS is on the first one,
with a capacity of 32GB. The 2nd, disk mounted at /itch, has a capacity
of 50GB.
Fedora17 was installed using its defaults, so the disks are physical
volumes and the filesystems all ext4 on logical volumes.
The tests removed all the jrb/rrd files before the run, and truncated
the column families inside cassandra. vmstat and mpstat were ran in the
background writing to their own log files, and killed off once the java
process had exited.
