The message being returned on the GU call was received by IMS before the start of this IMS execution. CF can be received on a CHKP call when an I/O area is specified for an MPP or message-oriented BMP. This occurs when a CHKP call issues an internal GU call. This DL/I code is only received by transactions that are eligible to issue commands.
This is an information-only status code.

If you look at IMS messages and codes manual you will find a chapter called 'About DLI status codes'. This chapter contains a chart listing the DLI status codes and the type of DLI call that can encounter them.
This chart shows that CF can be returned by a GU (message) call.
