[Opensymphony-oscache] Can I use multi cache instance instead of multi groups in cluster?

For high perfomance,I'd like to create a instance for every business category,for example ,I create thread instance for three purpose by following code:
[code]
GeneralCacheAdministrator cache1=new GeneralCacheAdministrator();
GeneralCacheAdministrator cache2=new GeneralCacheAdministrator();
GeneralCacheAdministrator cache3=new GeneralCacheAdministrator();
...
...
...
[/code]
I wonder if above code could work well in cluster,because I see many LOG info caming from resin server as following:
1.clustersupport.AbstractBroadcastingListener  - AbstractBroadcastingListener registered
2.325248 [UpHandler (NAKACK)] WARN pbcast.NAKACK  - [sun:2261] discarded message from non-member sun:2216

...

I just test the cache,I don't konw if I have followed the right way.
