Logged errors aside, the web server is responsive and
<localhost:19999/#menu_zfs_submenu_size;after=-864000;before=0> appears

– I lean towards closing this report as overcome by events … whilst I don't

netdata-related processes sometimes not stopping when they should at shutdown
or reboot time. I'll keep my eyes open for this.
