Intense JFFS2 testcase fails after 500 times

[Frederic Giasson]

Hi,

I tested JFFS2 with an intense test case, along with the chip driver I
written.  My testcase simply copy a lot of small files to the JFFS2
filesystem, erase them all and start over again util an error occurs.  

The first time I fill the flash, df command reports a 88% disk uasge.  It
remains like that until about 200 test case loops have executed.  But after
that, disk usage begins to grow slowly, and at about 520 loops, my testcase
fails, reporting a full disk.  After the test, I checked the flashes chips
and they are not burned out, they are still very good.  Did anyone ever ran
such tests?  If so, did it gave the same results?  If so, could there be
some sort of memory leaks with JFFS2 filesystem?

Thanks!
