Strange error after deployment - "Failed allocation for XX blocks"

Archive

Hi all,
today I face the strange behaviour of my FEZ Raptor. After uploading the application from VS2012 the debugger was quite a long time “silent” and seems not working and after this there is following in the Output window. It seems that garbage collector is trying something but without success. I have try to reset/unplug/plug again and the behaviour is the same.
Day ago I have uploaded this application a lot of time without this issue and now I have this problem. I am little bit disappointed by this behaviour because it seems there is quite often some new and new and new behaviour…

I am writing an application which should be of course as stable as possible because it will be used commercially for monitoring of some technology(GSM connection through RS232, another two RS232 communication, Ethernet monitoring(not yet implemented)) so I am afraid I am able to do this - but actually I do not have any other solution as HW and everything else is almost ready. So I hope I will be able to make stable application for my customer…

Thank for help.

Sorry, it was my mistake!
I was to eager to solve the problem with Debug.Print() while not connected to VS or MFDeploy so I have simply created my new Debug class with Print inside checking Debugger.IsAttached. Then I renamed it to MyDebug by VS feature Find and Rename and of course the inner Debug.Print() was also renamed to MyDebug.Print() so you can imagine the consequences…

Wrong code after Find and Rename (= my mistake)

using System;
using Microsoft.SPOT;

namespace MTC2
{
  public static class MyDebug
  {

    /// <summary>
    /// Print only when there is somebody listenning (VS debugger or MFDeploy Connected)
    /// </summary>
    /// <param name="stringToPrint"></param>
    public static void Print(string stringToPrint)
    {
      if (System.Diagnostics.Debugger.IsAttached)
      {
        MyDebug.Print(stringToPrint);
      }
    }
  }
}

After renaming inner MyDebug.Print to Debug.Print() everything works although I had to reset/disconnect/connect Fez Raptor couple of times to be able to upload new corrected application again:

but this was probably caused by that defect application previously uploaded…

Thanks for help!
