It's memory corruption on the VIP.

Almost impossible to troubleshoot without the crashinfo from the VIP and you said it didn't generate one. :(

Try and determine if there was any changes around that VIP about the time it reloaded.

By changes, do you mean config or someone working nearby who could have physically bumped it? I know from rancid that there had been no config changes in >24h from when the crash happened.

I meant anything.

data path changes routing table interface changes etc...

Very unlikely it was physical related since it was dealing with a special type of memory blocks. So I would suspect some internal change to the box such as "routing protocol flap, interface flap for that VIP, burst of traffic on that VIP, etc...". Something along those lines.
