A core file is an image of a process such as a GroupWise agent that is created by the Linux operating system when the agent terminates unexpectedly. A proper core file can help Novell Support determine why a GroupWise agent is having problems in your GroupWise system. See TID 3447847, How to Obtain a GroupWise Agent Core File on Linux,
in the Novell Support Knowledgebase.
