Are you going to do something about this memory consumption or is there
at least some kind of minimum expected memory usage you can give me?
I ran into an OOMEs the other day and the cluster was unable to recover
from that by restarting single nodes. The nodes couldn't synchronize
because of the OOMEs. I had to (jgroups-)disconnect all nodes from the
cluster and start a separate cluster which of course lead to data loss.
All of this happened because of some wrong memory consumption
estimations I made so in order to avoid that in the future I would like
to plan better ahead. Is there any other way to avoid such a cluster death?
Regards,
Christian

Those IdentityIntMap are caches meant to speed up serialization if
the same objects or types are marshalled again. It's normal for them to be populated
as marshalling operations are executed. We don't currently have a way to clear these
caches.
