Re: [Yaffs] data loss under heavy pressure on Yaffs2 GC

Hi Artis

I am very interested in this problem and will research it further, but at this
point I will make one observation.

I'm not sure it you realize this or not, but yaffs does collection on a block
basis, not a file basis. Therefore when it does a collection it just looks at
the chunks (bits of file) on the block being collected. If a file is spread
over multiple blocks then the parts of the file on the other blocks will not
get collected.

I would also like to ask some questions:
Are you doing interesting things to this file, like resizing, lseek and
overwrite etc?
Are you only writing a single file when this happens?
Could you perhaps send me the code that is running when the problem occurs?

Thanx
