      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.
