Unknown atom C_FOO for tag TAGNAME

This message means that a tag atom was used in Conductor NT or Process Portal B that we do not know about. We regularly add new tag atoms as we run into them.

As of DBDOC 11.2 Feature Update, there are new messages for tagatoms starting with "_" and ones with specious ")" character dangling.

This message shows a potential error in the system configuration, although most such errors prove to be harmless. It should be reviewed and hidden, unless it shows an issue that should be addressed.
