Dump in dbacockpit self monitoring

Hello,

we had a SQL Server 2012 and SAP 740 System.

If we choose Diagnostics/Self-Monitoring a dump is generated:

Application Component  BC-DB

Short Text

    Access using a 'ZERO' object reference is not possible.

What happened?

    Error in the ABAP Application Program

    The current ABAP program "CL_DBA_ACTION_SYSCHK_LIST=====CP" had to be

     terminated because it has

    come across a statement that unfortunately cannot be executed.

Error analysis

    You are trying to access a component with a 'ZERO' object reference

    (points to 'nothing'). Variable: " ".

    An object reference must point to an object (an instance of a class)

    before it can be used to access a component. The reference has either

    never been set, or it was set to 'ZERO' with a CLEAR statement.

Trigger Location of Runtime Error

    Program                                 CL_DBA_ACTION_SYSCHK_LIST=====CP

    Include                                 CL_DBA_ACTION_SYSCHK_LIST=====CM00B

    Row                                     5

    Module Type                             (METHOD)

    Module Name                             IF_DB6_ACTION_CONTROLLER~DISPLAY_VIEW

The System Landscape/System Configuration and Database Connection are valid and working. But Self-Monitoring is the Check Status grey ?

Any ideas ?

Thanks a lot
