[erlang-questions] cth_log_redirect crashed

Hi Roberto,

I've been reading through code but haven't been able to figure out how
the heck the system can end up in a deadlock. It's
application_controller that doesn't respond, but all
application_controller operations are asynchronous so it doesn't make
sense to me. I suspect it's rather an io-request/group-leader related
problem.

I went on to try to reproduce the error by running various stress tests,
but that didn't help either.

So, a few questions:

1. Do you get into this deadlock state each and every time, or does it
happen occasionally?

2. What process/function starts and stops the "goldrush" application?

3. Will you help me do some debugging on your site? I think I need to
make a dump! (what an inappropriate thing to say in any other
context...)  :-)

Thanks,
Peter
