RobotStudio event

Maxing out RMQ message size.

I have a Record that I am trying to send across from my .NET application to the RobotStudio. I progressively added a field and found that it stopped working because I got this error on RobotStudio:

41703: RMQ Error - Data could not be copied

The data type poseRecord exceeds the maximum size supported for the RMQ configured for task T_ROB1.

On the .NET side, my code looks like this:

ABB.Robotics.Controllers.Messaging.IpcQueue robotQueue = controller.Ipc.GetQueue("RMQ_T_ROB1");
byte[] data = System.Text.Encoding.UTF8.GetBytes(formatedMessage);
ABB.Robotics.Controllers.Messaging.IpcMessage sendMessage = new ABB.Robotics.Controllers.Messaging.IpcMessage();
sendMessage.SetData(data);
sendMessage.Sender = myQueue.QueueId;
robotQueue.Send(sendMessage);

byte[] data = System.Text.Encoding.UTF8.GetBytes(formatedMessage);

And data was an array of length 126. When I checked robotQueue.MessageSizeLimit, I found that to be 444. I was able to successfully send the record of length 123.

So I don't understand why this is failing. Also, I see that it is possible to edit the sys.cfg file to increase the limit to 3000. What is the procedure to do this?

I'm running this on RobotStudio 5.60
