Hi,
We are using Cassandra 0.6.12 in a cluster of 9 nodes. Each node is
64-bit, has 4 cores and 4G of RAM and runs on Ubuntu Lucid with the
stock 2.6.32-31-generic kernel. We use the Sun/Oracle JDK.
Here's the problem: The Cassandra process starts up with 1.1G resident
memory (according to top) b
This was my first thought, too. We switched to mmap_index_only and
didn't see any change in behavior. Looking at the smaps file attached
to my original post, one can see that the mmapped index files take up
only a minuscule part of RSS.

The sum of the sizes of all *-Index.db files in /var/lib/cassandra is 2924kb.

We have 10 key spaces, each with 2 column families.

s to keep the buffer
sizes small in order to reduce the impact of the leak. My patch takes
care of that.
I will post a link to the JIRA issue with the patch shortly.
