Hi,
Here's the output from when it freezes. Sorry it's a bit verbose,
wasn't sure what we're looking for so I've included it all:

This is very strange... looks like all threads are waiting for this
thread to finish compressing the data, but there is nothing in
WritableUtils, or even in the source of Deflater.java to suggest what is
happening... Could you connect a debugger, and run the process under
debugger? It would also help to get a couple of thread dumps and compare
them, if they look the same...
BTW. if you have a JDK 1.5 on that machine you could try running this
with 1.5 and see if it helps.
