consistantly corrupting a table

We run Online 5.03 on a Raid based SCO system. Our applications run 4gl runtime through Inet & Istar. We run a multitude of servers consisting of a server pair and up to 5 or so application servers all of them constantly doing updates and inserts to the servers. Our problem is that from time to time a particlular table gets the indexs corrupted. The corruption gets bad enough that we end up unloading the table, drop, create, and reload it. Dropping the Index doesn't fix the problem. This corruption seems to always occur on the same table. Before I get Informix software involved in this I was wondering what kind of things we could look at that could cause this. Any ideas? George Rachor george@ornews.intel.com -- George L.
