Heavy swapping can lead to timeouts, poor performance, and instance eviction.

Oracle Version 19.20.0.0.0 (Prod) / Version 19.3.0.0.0 (Test)

Upgraded from 11.2.0.4.

I see from time to time in alert log file following:

Prod:

Test:

As you can see it is quite rearly and at that time full backup was running. Is it something which should I address or it is safe to ignore ?
