I have to run a program for 8 hours but I get an error at different times during my program. this is the error.

Debug Error!
Program filename
This application has requested the Runtime to terminate it in an unusual way.
Then you can choose retry, ignore, cancel

when i hit retry i get:
The exception Breakpoint
A breakpoint has been reaches
(0x80000003) occurred in the application at location (0x00442572)

if i hit ignore it just gives the first error in my program and stops it.


Could this be a problem with my program or maybe a problem with something in windows?
any help is appreciated.
