When one device in a group is invalid (or cannot be written to for some reason), then it is found that the ability to log messages to other devices in the group is also affected. For example, say there were four ASCII text file devices in a group, and messages were being logged to that group. If one of those devices is invalid (for example, mapped to a non existent directory), then one or more of the other devices in the group may not be able to accept logged messages as well. 

CIT has confirmed this to be a problem. The problem has been fixed in Citect version 5.20 Service Pack A.
