Didn't recognize you as a fellow pegger. :-)

This is what I keep telling their support desk people but they keep
insisting it's bad hardware! :-)

The usual problem in a Progress RDBMS is when data are read and not
validated before use. Some people would rather have really high
transaction rates with spectacular crashes, than moderate
performance that doesn't even blink.

A worse situation is when the corrupted data are able to be re-used
and infect other data. Data cancer.
