You may notice deadlocks in the SQL Server Error Logs that are coming from the [ServerLog].[IdentitiesTable] and [ServerLog].[NamesTable] tables for the ServerLog schema on the K2 database.

Here is a snippet of the error:

Deadlock encountered .... Printing deadlock information

According to Labs, you can ignore the deadlocks as this is high throughput area that is mainly used for reporting and the system is designed there to retry if a deadlock is received as multiple areas of K2 pulls data from them.
