Andrew, Rohan, Garth, Markus,
Thank you for sharing your insights, pointers, etc. I'll need some
time to
struggle up the learning curve w/OS X, but it promises to be an
interesting
challenge. Given my available free time, it'll probably be a while
before
I get back to the list with any findings or follow-up questions.
Markus, to your point regarding the user-land Java app crashing the
kernel...
I couldn't agree more. There's been some bluster on the SF thread about
writing a virus when they figure out the issue, but I think that's idle
talk born of
frustration. The potential is pretty ugly, though.
As far as filing a bug, unfortunately, the Azureus developers and users
don't yet have a reproducible test case. It seems to be a frequently
occuring
intermittent problem with no clear causal event or condition. Anyone
with
a dual cpu mac and an extended time to let the app run (while
downloading
and seeding torrents) will probably see a panic, though. I'll see if I
can push
to get users to submit information to get a rough idea of MTBF or TDR
trends. It's pretty hard to get good data out of your average user,
though.
If anyone wants to talk about this off-list, feel free to contact me
directly.
Thanks again for the help.

A user-land app never ever should be able to cause a kernel panic.
Think of a java app embedded into a web page, causing your machine to
halt ...
If you have a reproducible case, please file it at

Unfortunately, my wife has only allowed me one Mac (so far)...
One guy on this list obviously was successful in setting up the remote
environment on a x86 box:

After making some modifications to the Darwin gdb codebase, I was
able to compile apple's gdb on a Debian 3.0 system, run it, and
connect to the OS X 10.3.4 kernel running on my iBook. Here's a
document describing how I did it:

And here's a patch for gdb-292 to make it compile and run on a Debian
3.0 system, and hopefully other Unix-like systems as well:
