I have experianced strange lockups sometimes.
In that case, 'xm list' shows no state for freebsd.
(usually it is blocked)
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 59 0 r---- 990.1
freebsd.sample 2 64 0 ----- 547.6 9602
I'd like to analyze this problem using debugger.
I found gdbserver binary in your web site but it seems old and
to require old libraries. Can I get the gdbserver source?
Thanks,
