Well, if you could run BIRD (presumably the current version) with
'ulimit -c unlimited' and then be able to kill BIRD during lockup
using 'kill -QUIT <pid>', then resulting core dump would be highly
useful for determining the source of the problem.

But hitting the BIRD in the right moment could be problematic. In the
next version, we will implement configurable 'watchdog' that would kill
BIRD automatically during such lockup.
