Hi,

Just an FYI if you didn't know already, FreeBSD 7.0-RC1 is
from
RELENG_7_0 src branch.  You might want to update it to RC2
(also from
same source branch).  Don't know if it will fix your problem
since I
don't use Azureus.

Regards,
Tommy

Two different people have responded personally to me alone
about 
different ways to get Java to try v4 connections instead of
v6 
connections.  This is completely irrelevant.  There is still
something 
broken in the Java runtime which spends all of its time in
v6 connection 
hell unless you disable v6 in the kernel.  Someone needs to
figure out 
why the Java runtime on FreeBSD does this.  I suspect some
thing in the 
runtime or in the kernel v6 stuff that is broken, but I do
not know 
where to look.

Azureus experiences the typical Java problem.  I could not
get anything 
to happen for quite some time until I realized that the Java
runtime was 
spending all of its time waiting for something to happen in
the IPv6 
connections it was trying to open.  I had to completely
remove IPv6 from 
the kernel.  Once I did that, Azureus magically started
working.

There is something major broken in the Java runtime hwich
causes 
everything to stop whenever you try to open an IPv6
connection.  Remove 
IPV6 from the kernel, and everything works.  When and if you
ever get 
real IPv6 connections in your machine, things might actualy
work.  For 
now, just remove it and move on.

You can also try adding -Djava.net.preferIPv4Stack=true to
the JVM command 
line arguments.

Do you have a reproducible isolated test case?
