Central UNIX Mail Server crashed on September 15, 1997 The Central UNIX Mail Server crashed on September 15, 1997 and was down until the evening of September 16, 1997. The reason for the crash was hardware diagnostics generated on two of the internal disk drives that comprise the root volume group (the disk volume that the system boots and runs from) and its mirrored backup. As a result of this outage, Internet mail destined for the Central UNIX cluster (including the OpenMail server) would have had delivery delayed until the evening of September 16, 1997. No mail should have been lost. Approximately 5000 accounts were missing from the system password file when the system came back up which would have resulted in any mail sent to those accounts being bounced back to the sender with a "user unknown" error. This error was corrected on the morning of the September 17, 1997. Senders will need to re-send the messages which were returned. If you are having trouble accessing your account, please try telneting to the session server, "polylog1", and verify that you cannot get in before calling the Helpdesk at 756-7000. An inability to receive POP mail is _not_ an indication of a missing account. POP mail is suffering from an unrelated bug. See system news article 9709MigrUpdate.
