I was just about to deploy a CHR, but in the last minute testing it's been rebooting whenever traffic starts to flow.
XenSever6.5 on intel X5650 CPUs.
I flipped every switch, went to the most basic config I could find with no solution, until I set the VM to only have a single CPU. Can't say for sure it's the fix, but it's been stable for a half hour now. Before, <=5Minutes and it would hard reboot.
