High "global cache blocks lost" statistics on one RAC node

I have a two-node RAC running an 11i-ebusiness suite (11.5.9/9.2.0.6 64-bit). I am seeing the following from Statspack:

Inst	Statistic                                             Total
per Second    per Trans


-----	---------------------------------------- ------------------

-------------- ------------

1.	global cache blocks lost                                 28
0.0          0.0
2.	global cache blocks lost                              4,410
2.7          0.9

We are using three giga-bit private interconnects going through a switch. This does not see like an interconnect issue otherwise, I think, I would have seen a higher number on the 1 node as well.

Any idea what might be causing it?

Thanks
Amir
