 No. The server is not in production and never was with FreeBSD 8.
 Only the kernel module is loaded, due to zfs_enable="YES" in rc.conf as
 a preparation for using ZFS with 8.0-RELEASE
 
 The problem described in the PR occured when zfs_enable="YES" was not
 set in rc.conf
 
 I see no direct connection to with this ZFS.

 I tested superpages on 7.2-STABLE with ZFS and had to deactivate them,
 after the server became instable.
