serialize()\deserialize() crashes

[tmptrash]

Good evening.

I have been working on serialization logic in my app last week and i found an asynchronous crashes in one of these two functions - serialize()/deserialize(). It somehow related to amount of requests and amount of data, which goes through socket. Because, if i send few data using my Client/Server modules, it works fine. So, on a high level i have a Server and Client modules, which do the job. Here is a server side:

include("../src/ImportFolders.jl")

import Config
import Server
import Connection
import Event
import Helper

function onBeforeResponse(sock::Base.TCPSocket, cmd::Connection.Command, ans::Connection.Answer)
  # this is response data for client
  ans.data = Array{Float64, 1}(100)
  # just server to client requests with some custom (Helper.Point) data to produce the issue
  for i = 1:1000 Server.request(sock, 1, Helper.Point(rand(1:200), rand(1:200))) end
end

con = Server.create(ip"127.0.0.1", 2000)
Event.on(con.observer, Server.EVENT_BEFORE_RESPONSE, onBeforeResponse)
Server.run(con)

I run it in command line like this:

julia -i --color=yes tmp\AppServerTest.jl

The client:

include("../src/ImportFolders.jl")

import Config
import Client
import Connection
import Event
import Helper

function _onBeforeResponse(data::Connection.Command, ans::Connection.Answer)
  # just some answer data for server
  ans.data = Array{Int, 1}(20)
end

con = Client.create(ip"127.0.0.1", Config.val(:CONNECTION_SERVER_PORT))
Event.on(con.observer, Client.EVENT_BEFORE_RESPONSE, _onBeforeResponse)

I run this using this command line:

julia -i --color=yes tmp\AppClientTest.jl

After correct running of client and server i use this commands on a client side:

Client.request(con, 1, 2)
Client.request(con, 1, 2)
Client.request(con, 1, 2)

They produce these errors on a server side.

  at index [0]WARNING: Server._answer(): MethodError(convert,(Tuple{Vararg{Int64}},symbol("")))
MethodError: `convert` has no method matching convert(::Type{Tuple{Vararg{Int64}}}, ::Symbol)
This may have arisen from a call to the constructor Tuple{Vararg{Int64}}(...),
since type constructors fall back to convert methods.
Closest candidates are:
  call{T}(::Type{T}, ::Any)
  convert{T}(::Type{Tuple{Vararg{T}}}, ::Tuple)

To be onest, there are many related to bugs to current, but this one is a most common. The same error sometimes occures on a client as well.

Thanks.
