Integration

My app was chugging along nicely when, out of nowhere, this Exception scrolled past. The app continued fine after that. I have one app that simply puts Order objects in a cache and another that listens for the related map events and changes a field with an UpdaterProcessor . It's just instances of the same class over and over. Everything is taking place on the same machine so there is no network involved. CPU is at 10% so nothing is starving for processor. How could I get this?
Thanks,
Andrew
