That was my first thought exactly! I halved the MAX_SPAWN_RATE to 16 (from 32) and then *exactly* the same thing happened; it only took a minute longer to happen .... If i recall correctly (not sure anymore since it was middle of the night) other processes also got blocked (hence i couldnt use keyboard anymore). That was why i figured it was some kind of lock/block/mutex/whatever inside the kernel....
