Crashes with EXC_BAD_ACCESS with Garbage Collection after hours of running

Question

i have a app where several videos are being randomly displayed and everything was sweet and worked great. Since they program loops the same code over and over again I find it very odd that is just stops all of a sudden. What can the error message below be about?

But after many hours it crashes. The first time it ran for 13 hours before crash and tonight it crashed after 11 hours.
