VMMotion and StorageVMMotion does not seem to affect the stability. Even  
deleting the VM, rebuilding from scratch, re-installing all packages from  
scratch, copying over a few configs and then copying in any other data  
(perhaps website data) does not solve the problem.

However, our two most notorious for crashing happen to be webservers. We  
moved one to hardware. We simply rsync'd the exact data (entire OS and  
files) off the VM onto hardware, made a few config changes (fstab, network  
interface) and it's been running for 4+ months now with zero crashes.

I don't think it's corruption :/
