Hi Christian, I had similar issues when building camel-cassandra on a Linux box with Java 7. Cassandra spawns a huge amount of threads when running the component's unit tests. The problem was caused by not having enough file descriptors available to spawn new threads. This eventually led to the error message as described in your post. After increasing the number of file descriptors per user all tests completed successfully and I was eventually able to build the component. I used the following configuration in my limits.conf, but you may need to use other configuration facilities on your OS X machine:
== /etc/security/limits.conf ==== * soft nofile 32768 * hard nofile 32768 root soft nofile 32768 root hard nofile 32768 [...] ======================== Hope this helps.
