Description
I have tried async replication scenario with async marshalling (optimistic transactions) and this has occurred:
04:34:15,182 ERROR [org.infinispan.remoting.rpc.RpcManagerImpl] (OOB-77,edg-perf11-48420) ISPN000073: Unexpected error while replicating

Seems that StateRequestCommand is iterating through all transactions' locked keys but the collections of these locked keys can be modified by interfering prepare/commit.
