Wierd semi-freeze

SDL Development
1

I’ve written a game that uses SDL and OpenGL, and under Linux every so
often it’ll freeze. Not just the game but everything freezes. The
little diagnostic LEDs on my motherboard, which normally flash all sorts
of numbers when Linux is running stop flashing. It’s frozen. But after a
few minutes everything suddenly starts working again, like nothing had
happened.

I have no idea what’s causing this. I’m using SDL 1.2.5, SDL_mixer, and
SDL_image. My graphics card is a GeForce 2 GTS with latest drivers.

Sounds like a driver and/or X issue, or maybe simply that you stress the
memory subsystem too much. (If you run out of RAM, and especially if you
run out of swap space, some kernels don’t behave too well. It may take a
good while before the kernel gets around to deal with the situation -
although at that point, you would normally notice that some process is
killed…)

Are you seeing this with other applications? Any certain feature that
seems to trigger it? Tried any other driver version, library or X
versions? Are you sure you don’t have mixed versions of some stuff? Tried
your program on another machine?
