TSXZS0011 User selected Cancel on disconnect dialog.

If a user tries to disconnect from the z/Server while MVS edit sessions are still open in the client, a confirmation dialog will come up to warn the user that the editor(s) will be closed before disconnecting. If a user selects "Cancel" in this dialog, the disconnect action will be aborted and this message written into the error log.

User Response:
No user action is required since cancelling the disconnect action was probably intended. If not, close any open (non-local) editor or disconnect again and press "OK" in the confirmation dialog. Unsaved changes can still be changed (individual confirmation dialogs will open).
