You should upgrade to the latest Sun JVM. OpenJDK is almost a year
behind in bug fixes.

It is a 64 bit VM. I didn't notice the hs_err_pid.log files since I'm staring
over ssh, so they're in my home directory instead of my working directory.
I've attached one of those below. I don't know much about Java, so I'm not
sure how to interpret this file.

If this a 64bit VM?
A 32bit Java VM with default c-heap settings can only actually use
about 2GB of Java Heap.

If it's a jvm crash there should be a hs_err_pid.log file left around
in the directory you started Cassandra from.

Oh, forgot this detail: I have no swap configured, so swapping is not the
cause of the crash. Could it be that I'm running out of memory on a 15GB
machine? That seems unlikely. I grepped dmesg for "oom" and didn't see
anything from the oom killer, and I used the instructions from the followi
It looks like MAX_HEAP_SIZE is set in cassandra-env.sh to be half of my
physical memory. These are 15GB VMs, so that's 7.5GB for Cassandra. I would
have expected that to work, but I will override to 13 GB just to see what
happens.
I've also got the JNA thing set up. Do you think this would c
The key JVM options for Cassandra are in cassandra.in.sh.
What is your min and max heap size?
The default setting of max heap size is 1GB. How much RAM do your nodes
have? You may want to increase this setting. You can also set the -Xmx and
-Xms options to the same value to keep Java from having
I'm using Cassandra 0.7.5, and uploading about 200 GB of data total (20 GB

total of about 50MB per batch. When I upload a smaller 2 GB da
