Ok, next step: get a thread dump from Java. On the terminal:

Wolfgangs-MacBook-Pro:eXist-develop wolf$ jps
23637 Jps
22071 start.jar
Wolfgangs-MacBook-Pro:eXist-develop wolf$ jstack 22071

This will produce lots of output. Just check for threads referring to org.exist.something in their stack. If you canít see anything obvious, send me the trace.
