[nicejoinworlds]

Hello there!

with this code:

Sub ExecuteRemoteQuery(Query As String, TaskId As Int)
   Log("ExecuteRemoteQuery: " & Query & " TaskID:" &  TaskId)
   If TaskId = 1 Then
     Dim job As HttpJob
     job.Initialize(TaskId, Me)
     job.Download2("http://www.domain.com/tareas/app1.php", Array As String("cadena", Query))

   Else
     Dim job As HttpJob
     job.Initialize(TaskId, Me)
     job.Download2( "http://www.domain.com/tareas/app-1.php",  Array As String("cadena", Query))

   End If

End Sub


Sub JobDone(job As HttpJob)

   Log("Back from Job:" & job.JobName )

  If job.Success = True Then

     Log("Job:" & job.JobName & "Success OK" )
     Dim res As String
     res = job.GetString
     Log("Response from server: " & res)

     Dim parser As JSONParser
     parser.Initialize(res)

     Select job.JobName
       ....
     End Select
  Else

    Log("Error: " & job.ErrorMessage)
  End If
  job.Release
End Sub

This error can happen when you don't check that Job.Success is true or when the job is released multiple times. Your code looks correct though not all the relevant code is posted.

Thanks people,
The problem are (like Erel explain) job was released multiple times

I rewrite the code to know exactly when I generate a JOB and finally, the real problem was that job.GetString show the error [open failed: ENOENT (No such file or directory)] if the job not return nothing.
I soved it asking job.GetString inside of the [Select Case] if I wait somthing

Sub JobDone(job As HttpJob)
   
    Log("Back from Job: " & job.JobName )
    Dim res As String
   
   If job.Success = True Then

    Log("Job:" & job.JobName & " Success OK" )

    Select job.JobName
                   
        Case A 'no waiting answer form the job execute
                       ....

        Case B 'waiting answer form the job execute
            res = job.GetString
            Log("Response from server: " & res)
...
