      Everytime I add IO counters in htop on XOA, it stalls and crashes. It also caused a VM being backuped to reboot.

      What's more, the backups are listed as ongoing after a force-reboot of xoa, though I do not think they are actually running as there is no network or disk I/O.

        A toolstack restart cleared the ongoing-but-failed tasks.
