The following reply was made to PR bin/17134; it has been noted by GNATS. From: Todd Hansen <tshansen@oceana.nlanr.net> To: Guy Helmer <ghelmer@cs.iastate.edu> Cc: Sheldon Hearn <sheldonh@uunet.co.za>, FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: bin/17134: problem with cron forgetting jobs Date: Fri, 3 Mar 2000 11:56:05 -0800 (PST) I will see what I can do with our systems to help you.
