The CPU usage (and also some recurring disk usage) had been that high for quite a couple of months on one of my DiskStations (a DS112+), and esp. the disk usage (preventing the disk from hibernating) had worried me quite a lot.

Thanks, Synology, for stealing a couple of thousands of hours of lifetime from that NAS disk!
