Compiled program stops responding after normal operation

Hello, I have a problem with the Matlab Compiler (mcc), which is that a compiled program suddenly stops responding after it has been running normally for a long time. It may happen after 1 or 2 days of up-time. I don't get any error messages, and the program window (it's a GUI built with GUIDE) is still visible, however totally unresponsive. The program does not consume too much memory (< 1 gb), but it does write to the disc from time to time.

I am using Matlab R2011b. Can anyone assist?

What OS are you using? If Windows, did you run the executable in a command window to see if it returns any error messages? If not, you should do so.

Hi, I am using Windows 7 Pro (64 bit), but the executable is built as a 32 bit application. I have a command prompt (console application), but I am not sure it will output error messages the same way a windows command prompt, so I'll give it a go.

I am wondering, if there is an upper limit to the total data that can be saved in a matlab session? I can see that the data that I saved before crashing is approximately 2 gb (spread over several smaller files). It may be just random, but then again, I am looking for something that happens after a long time (corresponding to accumulating large amounts of save data).

A 32-bit application cannot use more than 2GB RAM. There are ways to raise this using the 3GB switch
