Help, HA is slowly dying

Running HA core on docker for many many years on a NUC i5. Now, it seems something bad is going on.
HA response got slower and slower. DB disconnections: got an error readying communications packets (I am using MariaDB 10.8). Timeouts more and more: Setup timed out for bootstrap - moving forward, components/hunterdouglas_powerview/shade_data.py:74 Error doing job: Task exception was never retrieved.
It is getting worse and worse. Today, half of my Zwave devices seems died in HA. Fortunately the came up after reboot and long waiting.

How could I best diagnose what’s going on? What is blocking Home Assistant from wrapping up the start up phase?
Any ideas are welcome!

How big has the database grown? Are you SQLlite, Maria, or other for the database? Are the hard drives eMMC which have a short life versus other hard drives?

I am on MariaDb and started over with an empty database

What does the storage settings report on memory usage and eMMC life?

How can I get information about this?

Found some information. These are my results, but I don’t have a clue if this is indicating a problem:

Okay left panel, Settings>Storage> 2 items should be listed, What is used/total capacity and life used and remaining on the eMMC drive

Since I am on Core, there is no Settings/Storage for me. I do value your suggestion that my eMMC could be weared to much., so I will try to move HA to another nuc that I have, and see how it behaves
