Carl, Just out of curiosity, have you tried building out machines with DIFFERENT hardware. E.G. building out a server using an IBM or HP computer, rather than than the ones you already have. If I recall correctly, you started this thread out with SIG 11's. SIG 11's on Linux are quite often hardware problems. I know you've done memtest, but sometimes that's not enough. Here's a link to a problem I had: http://archive.lug.boulder.co.us/Week-of-Mon-20071210/035903.html To make a long story short, there was random disk corruption that was happening. When I stopped using the on-board controller and went to a PCI one, the computer would reboot itself under heavy load. Some of the static burn-in utilities can miss hardware defects because they don't actually stress the system. E.G. power, CPU, disks, etc. The problem was a specific rev of a specific motherboard. I think you need to step back, get a computer from a different manufacturer and test. You've tried different OS's, different JVMs, different everything, but different hardware. By your own admission, the app used run flawlessly on an older server. When you've eliminated everything else, the thing that remains, however unlikely must be the culprit.
