named won't run anymore

[Bastian.Zacher at aspect-online.de]

Hello NG,

my named server won't run anymore. It produces a core-dump right after 
starting and terminates itself. Perhaps it terminates while receiving the
first query? I'm using isc-bind v9.2.3.


Neither a upgrade nor any changes to the configuration was done. Bind 
stopps
abruptly.

here are the last lines of named.log:

Thanks
