Debugging "Dispatching event to subscriber 'org.openhab.core.internal.items.ItemUpdater - takes more than..."

Hi, I am trying to debug the repetitive error messages
Dispatching event to subscriber 'org.openhab.core.internal.items.ItemUpdater@15071f5' takes more than 5000ms.
I get them only for a specific item. How do I find the Item referred here? I thought “15071f5” should be some database ID but I have no clue how to query the Item name using this value. It’s OH 3.0.2 with InfluxDB persistence. Thanks in advance,

You’re sure about that? These messages are often seen when the whole system is on the verge of grinding to a halt, but of course then refer to several different Items.

Can you work out a likely culprit? Something that gets updated often, something that is connected with a possible long-running process like external HTTP, something that does update shortly after the message.

As always, be aware that the task complaining might not be the guilty party, because it is blocked by something else hogging resources.
