This looks to me like a classic off-by-one error

Actually, they said it was the difference between the number of files the flash could handle vs. the physical size of the files. That is: The memory isn't full, but it's out of file handles.

That's what they say... but this is the same crew that said: "ooops, we calculated in feet but programmed in meters!" (Or vice versa).

OK, that's another way of saying the same thing. A file handle is just an address. The handle is a number that takes memory to store. Someone determinined the maximum number of files and allocated a certain amount of memory to store the file handles. There appears to have been no check to prevent exceeding this number.So when the one-too-manyth file handle is added it overwrites something important in memory. Result is a reboot.

As an old "c" programmer, I know this one quite intimately. When you have to squeeze a lot of code into a tiny amount of memory, you put the obligation on the user not to break things.
