1. what are the possible causes?

2. what is actually happening? (looking for a relatively technical answer)

3. what is the recommended solution to fix it?

One answer, tuffet adjustments.

Valve seats not properly seated can and could cause to make some knocking sound. Valve clearance needs re-adjustment after some period.

When i experience detonation, is usually check the following:
- fuel (switch to higher octane or another brand)
- ignition timing (check and retard by around 2deg)
- spark plugs (switch to one heat range colder)

These are the usual culprits that can be singled out first before going on to other possibilities.
