I had a server panic Saturday night and shut down. When IDS was manually restarted Sunday morning, it came up fine and commited 4360 rows This is IDS 9.4.TC2 on Windows 2000. This has never happened in the 3 years the server has been running. Why would this happen? Should I be concerned that a drive is going out?

Does any kind of overnight anti-virus scan run that opens the chunk files?
