Ryan Emerson commented on ISPN-7308:
------------------------------------

[~rmacor]I believe that this is a result of insufficient memory, is it possible to increase the heap size when running the experiments to see if this resolves the problem? 

I found the following in the logs which corresponds with the experience of [others|https://github.com/EsotericSoftware/kryo/issues/448]:
