Hi!
I'm currently trying to write an application using the IA94: IBM Message Service Client for C/C++ version 2.0.1.0.
I'm running Windows XP and MQ 6.0.2.8.
If I run the provided SampleConsumerC.exe in parallel with two different users, I get the following FDCs:

The SampleConsumerC.exe works though, and is able to receive messages.
I stumbled upon this with my own application and tried to reduce the code as much as possible. So I just tried the sample applications and there I face the error as well.
If I run two instances of SampleConsumerC.exe with the same user, no error occurs.
I searched the forum, but everything that seems close (e.g. shared memory) seems to deal with the server, not the client. But maybe I'm just confusing things here...
Any ideas?
Thanks,

Sounds like there's a thread problem with the connection. And that sounds like a PMR.

Hi!
Thanks for you response! PMR is problem-management-record, isn't it?
Do I need a support contract for that? Where can I open a PMR?
Thanks! |

The relevant portion of IBM's website. Or by telephone, at the phone number found on the relevant portion of IBM's website.
But talk to your IBM Sales Rep. |

| From the FDC report, it looks to a problem in trace initialization. Trace uses shared memory. I have been running XMS on Windows XP SP2 and don't see any problem. May be there are issues with Windows XP SP3. |

Hi!
I've got severeal machines here showing the problem: All are running Windows XP SP3 or Windows 2003 Server R2 Service Pack 2.
By the way: Is it possible to disable FDC generation alltogether? |

AFAIK no and why would you want to? It's like turning off the fire alarm because the constant ringing is annoying you.
