What OS r u using client & server. Do u have oplocking & read caching disabled.

If server downed is it being shutdown properly. Had case in last month where client just logged off and then turned power off, cache not being written back to disk = corrupted database. Required onsite visit to find out what was the problem. No problems since.

Are you using autoinc or pull the ID's from a control file ?
Caching can cause this.

Check to see default sort order in DBC

Could also be caching.
