[Madhu Venugopal (vmadhu)]

Precisely, it is simple.

I have 2 nodes in the cluster & I have 1 TRANSACTIONAL cache.
At the very same time (few millisecs apart, both the nodes starts to write
key/value into the cache.
Both the nodes write the exact same Key, but different values in each Node.
I just have 6 keys/values to write. But just after 2 or 3 entries, I see
this exception.
Since this is happening in a different thread (and not in the thread that
writes the K/V in the cache,
I am not sure which operation causes this.

Let me look @ the iSPN that you pointed out.

Thanks,
-Madhu
