Hard to say, but heat can be a real killer. The NASA pdf on NAND flash memory specifically tested them at the extreme rating. Most of the chips in these units are rated for 80c (the exception is the USB chip which is ~20c higher). Why bother?
In terms of memory errors I'm seeing, the QLD sourced
ICC has a lot of ECC errors. The VIC sourced
ICC had some, but less (and they are disappearing - I assume the driver has decided to remap sectors - but that's the newer firmware). My ACT one (1/8 the flash memory size though) has heaps - and not disappearing - old firmware again.
I've been learning about QNX and how to tell what's going on under the hood, it seems the non-nav version (mine) uses about 60% of available RAM. The media-player still crashes. The output is less than the newer firmware - i.e no details. Killing the process and running it as root does give an extra message though - Memory fault (core dumped). It's not running out of memory - one of the dynamically allocated buffers is being overrun. I know this because I've extended the static buffers out to 10MB (and it still all loads - so plenty of memory available - about 110MB) so static buffers are not being exceeded.
Some of the checks I've seen in the code about reading music files say 4,999,999 is the absolute limit. But I think the programmers have added their own crap logic to the shuffle function using fixed buffers - then limited it to 1000 files. Morons. But like the hardware side, I have not given up.
There's two things I want from the
ICC screen - a decent music player and good navigation.
