OK so to confirm that I understand correctly: 6 days per week the computer starts up, writes its log files, and shuts down correctly. 1 day per week the computer starts up, does not appear to write its log files, and hangs up. Is that correct? If so, have you examined the log files on "the bad day" while the computer is running? Are you running the computer with a read-only root and using /tmp for storing /var while running? And expecting the shutdown process to copy the files in /tmp back to /var? If so, that may be why your files appear not to be written - because they are not copied back on shutdown.
