UUCP has two types of error messages: ASSERT and STATUS.
When a process is aborted, ASSERT error messages are recorded in /var/uucp/.Admin/errors. These messages include the file name, sccsid, line number, and text. These messages usually result from system problems.
STATUS error messages are stored in the /var/uucp/.Status directory. The directory contains a separate file for each remote machine that your computer attempts to communicate with. These files contain status information about attempted communication and whether the communication was successful.
