my application closes automatically after a long period of time (about 12 hours)

Hi,

I have developped an application which scans the inbox of my E71 device continuously. It waits for some specific formatted SMSs, and it performs specific actions according to the content of the SMS body.
The application is supposed to run for a week without the need to restart it. It works very well for a day. But every morning, I can see that my application has been closed. I've put a lot of try catch within my code, so I can say that no exception has occured during the night.

My question is: what is causing my application to be stopped? Is there a kind of system process on the phone which closes my program?

Thanks a lot for your help.

Have you tried to insert log file to track every important action?

Very likely it's running out of heap.

Thanks for all your replies.
I'll improve my log file system and make additionnal tests...

What kind of tool can I use to monitor system resources ?
