Hi there,
I'm doing some tests upgrading from 4.8.6 to 4.9.0 (and also 4.9.1) and
I'm having some issues with bind 9.10 in a debian 9 vm.
When Bind is running, if a machine updates, it crashes with the
following error:
/kernel: [ 7948.941528] named[22947]: segfault at 0 ip 00007ffa89f87a50
sp 00007ffa8c6588a0 error 6 in
libdnsserver-common-samba4.so[7ffa89f82000+9000]/
Also, when it's running (before crashing), I neither can enter at DNS
(nor group policy objects) through RSAT. In log.samba, the following
errors are logged:

I looked for an answer but couldn't find any, I think it's a recent
problem or I'm doing something wrong...
Sorry if the email is too extensive.
Thanks.
