i386 isc-bind shutdown problem

Hallo Ports Team,

recently I upgraded the isc-bind package from the i386 packages-stable 
directory:
isc-bind-9.20.24v3 to isc-bind-9.20.26v3
All relevant libraries were also upgraded.

But isc-bind-9.20.26v3 does not shutdown cleanly.
isc-bind-9.20.24 did shutdown cleanly.

I use a thin client, OpenBSD i386 7.9, with isc-bind
as a forwarder.

Beside that isc-bind-9.20.26v3 workes correct.

Starting isc-bind-9.20.26v3 with "/etc/rc.d/./isc_named start" generates
[ 1 ]
in /var/log/daemon. I dumped only a few lines further down of it.

After "/etc/rc.d/./isc_named stop it generates some error lines,
as you can see further down.
[ 2 ]

Of interest, I think, is liburcu:

i386 / amd64 packages-stable had at that time liburcu-0.15.6p0 listed.

Under [ 3 ]
I listed the first lines of the +CONTENTS file
in the /var/db/pkg/isc-bind-9.20.26v3 directory of the i386 box.

Under [ 4 ]
I listed the first lines of the +CONTENTS file
from the amd64 packages-stable isc-bind-9.20.26v3.tgz.
It needs libcuru-0.15.6p0 !!

I do not have isc-bind installed on a amd64 box.
So I dont know, if its compiled with liburcu-0.15.6 or 0.15.6p0.
