A few days ago we had problem with one of our CP owned disk which crashed the machine. The machine came up without the disk until the problem was fixed and the disk was attached to the system. Meanwhile FAL was running. Our host tables happened to be on the bad disk! The SMTP mail service rejected all messages destined for ".cmu.edu" domain with unknown host reason. This continued for a few hours until someone noticed it! I suggest that FAL should exit in cases such as these to prevent some of these problems. I have added code to our system to check for these to make sure no mail messages is lost (at least for smtp). Thanks postmaster@cmuccvma
