hi, i'm running my own app and the error rise whe i switch quikly from one menu to another withot let that the page ad been loaded.
i think the that error rise in the
B4X:
Sub Page_ParseEvent(Params As Map)
    Try
    Dim eventName As String = Params.Get("eventname")
    Dim eventParams() As String = Regex.Split(",",Params.Get("eventparams"))
    If SubExists(Me, eventName) Then
        Params.Remove("eventname")
        Params.Remove("eventparams")
        Select Case Params.Size
            Case 0
                CallSub(Me, eventName)
            Case 1
                CallSub2(Me, eventName, Params.Get(eventParams(0)))                  
            Case 2
                If Params.get(eventParams(0)) = "abmistable" Then
                    Dim PassedTables As List = ABM.ProcessTablesFromTargetName(Params.get(eventParams(1)))
                    CallSub2(Me, eventName, PassedTables)
                Else
                    CallSub3(Me, eventName, Params.Get(eventParams(0)), Params.Get(eventParams(1)))
                End If
            Case Else
                ' cannot be called diretly, to many param
                CallSub2(Me, eventName, Params)              
        End Select
    End If
  
      
    Catch
        Log(LastException)
    End Try
End Sub

but this is only an idea. it is hard to give you my code because the project is big and is in production.

yes.
i have tested it.
Alain(alwaysbusy)

write me that "closing the page before it is finished may confuse the jetty server so I will have to see if there is something I can do or if it has to be solved by Erel on the server side.
"

In first post i have reported the log of the server when it go on error and after during a new call from a client.
Erel, this accours often in a centos linux server and with the last release of your b4j.
I use mysql server as database and i connection pool closing all regulary.
