Identity server 4 - error The incoming tabular data stream (TDS) protocol stream is incorrect. The MARS TDS header contained errors

V4.0.2

We're receiving spontaneous peaks of errors, that are only shown in application insights, such as:

Microsoft.Data.SqlClient.SqlException (0x80131904): The incoming tabular data stream (TDS) protocol stream is incorrect. The MARS TDS header contained errors.

For the following query:

SELECT [p].[Key], [p].[ClientId], [p].[ConsumedTime], [p].[CreationTime], [p].[Data], [p].[Description], [p].[Expiration], [p].[SessionId], [p].[SubjectId], [p].[Type] FROM [PersistedGrants] AS [p] WHERE [p].[Key] = @__key_0

Any suggestions?
