Exchange 2013 multiple event id 10010 Mid-Tier Storage

I notice repeating events with the id 10010 for the source "MSExchange Mid-Tier Storage" on the Exchange server.

In the description are different things like:

• Process: MSExchangeSubmission (6496), Db:14f63545-f85d-45dd-a9cc-d457dbb7d046,C:1,BT:00:00:00,
• Process: MSExchangeDelivery (3020), Db:14f63545-f85d-45dd-a9cc-d457dbb7d046,C:2,BT:00:00:00,
• Process: Microsoft.Exchange.RpcClientAccess.Service (9248), Db:14f63545-f85d-45dd-a9cc-d457dbb7d046,C:2,BT:00:00:00,

Is this normal or what is wrong?
