When using a pre-1.6 MSSQL agent plugin the "mssql_blocked_sessions" check plugins would crash during discovery.

The pre-1.6 MSSQL agent plugins are now deprecated and can no longer be used. Old still existing services will go to "UNKNOWN" and encourage you to update to a newer agent plugin version. After a rediscovery the old services will vanish and new services will not be discovered.

Therefore an upgrade as described in Werk #6140 is necessary.
