There were a couple of new notifications this morning. The database size had grown to 9 rows. CPU usage was up again. I cleared the notifications, the databases back to 4 rows, and CPU usage is high again:

This is ridiculous. Nearly 70% CPU for such a tiny dataset

Please advise whether it’s ok to let our engineer has a remote session to check it. Please contact support team to confirm it.

I don't allow Internet access to or from my NAS and I don't want to switch it on. So I don't really see how a remote session would help?

If I look at info using redis client I can see the following:
rdb_changes_since_last_save:203
I have looked at this every day since realising that it was potentially an issue with redis. It is always around 200 and sometimes more. Yesterday it was 279. I still suspect that redis is scanning all my data and not just notifications.

Do you have Clam installed? I get CPU exceeded 100% admin notifications overnight. There's no detail. When I shut down Clam, the notifications don't happen.

No. To install applications I would need Internet access

So that's nearly 200 changes since this morning with no Internet access…

My husband uploaded some files to our media folder. He's not sure how many. I'm still certain that Redis is scanning all my data. I would understand that if it were in itself a virus scanner designed to protect my NAS. As it stands it feels like quite the opposite.
