I am receiving the following error in the TAG MCS LCA.
GQI error: Error in implementation of OnStartUpdates: Failed to setup a connection with the DataMiner Agent: Cannot clone non-authenticated or non-regular connections
Is this a GQI issue or is this a configuration issue of the TAG element? 
Hi Randy,
This is probably an issue in the TAG MCS LCA. See DCP task 292245.
This issue occurs when the connection provided by GQI in the OnInit method is stored in a variable. That connection is disposed once the ad-hoc data source finishes executing. If the code later attempts to use the same connection, it can result in this error. If an SLNet connection needs to be used beyond the lifetime of the ad-hoc data source execution, the connection should be cloned first, and the cloned instance should be stored in the variable instead.
Thank you for detailed response Tom!
