-----------------------------------
    Description: 
Hi,

I'm going to  upgrade to Infinspan 7.2.1final but I got into a showstopper. This error occours very frequently and the cluster becomes not usable.

In dev enviroment I'm using only Java HotRod clients and 3 Java HotRod Servers. When I put a "byte[]" in a cache then the following error occurs.

Using only one Hotrod server the error does not occur.
