>I've seen this happend and I believe that it's result of hardware or network failure/problem/fluke. I never was able to trace the source of such corruption and it didn't repeat again in following days.

I'm getting it twice a week, but always at different installations. Different client site, same software, and its always on the same table.

If it was a hardware problem, I don't think I would see it so frequently on one table, and never on the mnay others.

Thanks for the try, Sergey.
