I cant persist large data in PersistentFSM

Akka
1

Hi

I’ve currently been involved in a project that uses PersistentFSM that connects to a local akka.persistence.journal.leveldb but they cant save large value only write and read character d and c and why cannot write f character

 var actorSystem = ActorSystem("ActorSystem")

  def repeatChar(char:Char, n: Int) : String = {
    var result = ""
    for(_ <- 1 to n){
      result += "" + char
    }
    result
  }

  var actor = actorSystem.actorOf(Props[OutBoundFsm], "PropExample")
  val rs0 = MailBox(List(repeatChar('c',100000)), "other",None)
  actor ! SendToMailBox(rs0)
  val rs1 = Items(List(repeatChar('d',200000)), "other",None)
  actor ! SendToItems(rs1)
  val rs2 = Items(List(repeatChar('f',300000)), "other",None)
  actor ! SendToItems(rs2)

  actor ! GetCurrentItem

this is my config file :

persistence {
        journal {
            plugin = "akka.persistence.journal.leveldb",
            leveldb {
                dir = "target/items/journal",
                native = false,
                fsync = on
            }
        },
        snapshot-store {
            plugin = "akka.persistence.snapshot-store.local",
            local {
                dir = "target/items/snapshots"
            }
        }
    }
    actor {
        serializers {
            java = "akka.serialization.JavaSerializer"
            # Define kryo serializer
            kryo = "com.romix.akka.serialization.kryo.KryoSerializer"
        },
        kryo {
            type = "graph"

            idstrategy = "incremental"

            buffer-size = 8192

            max-buffer-size = -1

            use-manifests = false

            use-unsafe = false

            post-serialization-transformations = "lz4,aes"
            implicit-registration-logging = false

            kryo-trace = false

            resolve-subclasses = false
            mappings {
                #"package1.name1.className1" = 20,
                #"package2.name2.className2" = 21
            }
            classes = [
                "framework.Items.DomainEvent"
            ]
        }
    }

why cannot write this line (below)

  val rs2 = Items(List(repeatChar('f',300000)), "other",None)
  actor ! SendToItems(rs2)`**

and built.sbt

`  "org.iq80.leveldb" % "leveldb" % "0.7",
  "org.fusesource.leveldbjni" % "leveldbjni-all" % "1.8",`

what is the problem in my source ?`
